Summary Force occurs in either push or pull mechanisms, which occurs in straight lines while a torque occurs in a circular manner. The report focuses on the push mechanism, which is force applied on the three designs in the experiment. The push force is the key mechanism that leads to the motion of the objects as shown in the three designs below. Force is applied through the push block in the three designs given. However, the push mechanism in the three designs occurs in different positions, which leads the directions and distance the loads move. The report presents that design A of the three given meets the requirements needed in terms of the compliance check provided including ease of use and flexibility among others as presented. 2.0. Report Analysis The report presents the mechanical advantage that exists when the push mechanism is applied to a lever to move the load applied on the lever. The point of applying the push mechanism is to make the work easier. The report presents an outline of the three designs used to show how the push mechanism can be effective in increasing efficiency. It considers Newton law, which stipulates that for every action there is an equal and opposite reaction (Singh, 2010). The conceptual designs provided show how the push mechanism is important and plays an important role as well as the designs for the efficiency of the given levers. The designs are as follows: 2.1. Design A Design A as presented above, is structured around the push block, which increases the function of the lever. The mechanism in this structure involves central structures such as the pivot pin, the rod connected, and lever as presented above. The asembly plunger of the design can have the horizontal guided movement of 30mm with the capacity of returning to its original position when the lever is released. The design lever has an angular movement of 45o. To achieve the desired motion of the design A, bending and shear stresses in the elements perceived is included. For instance, the rod end and the lever among other componets assist in the effective process of tranfering forces between the points. The push mechanism is used to ensure that they rod connected to the lever engages in effectively transfering motion. Design A is a first order lever where the effort and load are at the edges of the turning point. 2.2. Design B Design B, as presented above the weight of the load is transferred parallel through sing the lever. The 45o angle presents that the design of the lever is a perfect system thatcauses the centerlines of the two different points leading to the efficiency of the wheel. The load is between the turning point and the force, which brands it as a second order lever design (Ramakrishna, 2012). However, the distance that the load moves is way greater compared to the distance moved by the effort, which makes the mechanical disadvantage. 2.3. Design C All levers have a turning point, which is called the fulcrum. The force applied is given as effor, which does the work while the load is the force that is been pushed against. Thus, the main difference of the levers as given in the three designs is te position of the fulcrum, effort and load. The design C turning point is at the center of the load and the turning point, which brands it as a third order lever. 3.0. Discussion The experimental result shows that design A is the best for application due to the high flexibility, safety, recyclability, ease of use and others as presented in the table provided below.

The table presents that design A and C are more efficient and better compared to design B based on the features given. Design C presents a third order lever since it shows the effort placed between the load and the turning point. Design C is better than Design B because the load moves at a greater distance compared to the effort. Design A is better because of the load distance as well. This can also be attained through the ratio of velocity, which is given by the division of the distance moved by the effort against the distance the load moved (Ramakrishna, 2012). The first order lever presents how the forces react to the load on the turning point. When the forces are parallel, the perpendicular distance from the point of turning influences the efficiency of the apparatus (Singh, 2010). The push mechanism is given through the process where force is applied to trigger a motion. The three designs show the push mechanism through how the load is applied on the mechanisms to trigger the motions perceived. 3.1. Task 1 The three designs were developed through three tasks. Task one involved developing designs that would be operated by the push mechanism. The task involved making notes and sketched diagrams of the designs that can effectively be operated with the push mechanism. Design A, B, and C sketch is: In the sketch provided above, one perceives that the push force is applied in a straight line, which gives the development of the push mechanism. The load when applied to the apparatus, the lever has an angular degree level of 45o within the the three designs, which trigers the movement, and speed of the load as anticipated. Task one as presented involved developing conceptual designs that would use the push mechanism. The three designs as presented are different in terms of the od connected, and how they are connected. Design one has a straight rod, while the pin that shows the turning point is at the middle. Design B has a straight rod connected as well, but with more pivot pins to move the load applied on the apparatus more effectively (Shigley, Charles, & Richard, 2004). On the other hand, Design C has a straight rod, with bends, and a guide at the edge near the push block. The three designs developed are different in appearance, flexibility and performance. Thus, the first task was completed with the effective development of the three designs presented above, that will be operated using the push mechanism. The final design drawings of the three designs are given above. 3.2. Task 2 It involved engaging in a design analysis of the three designs developed. Based on the tabe 1, given above, Design A had the best flexibility levels, followed by C then B. This, could be attributed to the rod connected where design A had a straight rod, which presents that a load can be moved along the rod using the push mecanism easily. More importantly, changing direction of the load would be easy on design A, which shows that even in terms of usability, it is the easiest to use (Shigley, Charles, & Richard, 2004). On the other hand, design B has a pivot pin at the middled while design C has a bend. Design C is more flexible compared to B since the pivot pin cannot be adjusted, and when loads get to the middle more effort has to be exerted to move it to the next part of the rod, unlike C. Thus, design C is much flexible compared to B, which includes the usability of the machines. According to table 1, design A is better than B and C based on the features in the table including safety. Additionally, the table also shows that C is better than C in several features, except safety, and usability ease. Based on the features given in the table, the optimum design schemes of the three designs include manufacturing, maintenance and productions costs, ease of use, safety and flexibility of the machine. The features given in tabe were chosen for various reasons, which include their importance in the efficient operation of the apparatus. Flexibility is one of the most important features. It is analyzed in terms of flexible production costs and flexibility of using the machine. That is; through the movement of the load on the apparatus. Based on the given assumption, design A is flexible to fit different production needs since it has a flexibility in terms of moving different types and weight loads effectively in different directions (Chryssolouris, 2005). Safety is a key feature since prior to the application of the apparatus it must be deemed safe for use by the customers or clients. Thus, in this case, it is importnt to ensure the machine can effectively perform its tasks without causing any harm to the users. This can be ensured through guaranteeing pivot pins among other parts are connected stably to the apparatus, and that they can carry the weight of the load applied without engaging in destruction of the load, machine or harming the user. Reyclability is a social corporate responsibility that al machines are expected tomeet. That is, when machines or their parts are more recyclable, the more people engage in environmental awareness, which guards life by ensuring some products that are harmful to the environment such as chemicals to cause pollution of air, soil water or land are disposed effectively. The more recylable a material is, the better it is for use since it meets the legal requirements, environmentl requirements and social corporate responsibilities among others (Singh, 2010). Easy to use; when a machine is more easier to use, the more usable it is in a field. Thus, the simplicity of design A, makes it a better machine for use in various tasks. If the apparatus can be used easily to meet the set objectives while providing efficiency and satisfaction it shows it is a better utility. Production and manufacturing cost are some of the important design features of the apparutus since it is imperative that a high quality and satisfactory performance. It includes considering the cost of raw materials, labor and manufacturing supplies. The higher the costs of production/ manufacturing should meet the performance of the product. However, in this case design A has a lower manufacturing cost and high performance anticipated, branding it as one of the best products for the push mechanism in this exercise (Shigley, Charles, & Richard, 2004). Maintenance costs are also a key factor thaat influece the success of the product. The design A product has lower maintenance costs, which are also linked to the recylability of its materials, which brands it a better product. With the necessary servicing of the product, the life cyle of the product can increase. Thus, design A has lower costs of maintenance, including the low necessity of professional maintenance making it the best design. 3.3. Task 3 Task 3 involved engaging in an optimum design solution compliance check, which showed that design A was the optimum design solution. Based on the table below, one perceives that design A met all the necessary compliance check solutions, when linked to the push mechanism. 4.0. Conclusion Design A, was the best solution since it met the necessary compliance check solutions needed. More importantly, the design detailed analysis showed that design A was better in all the chosen features such as flexibility, production and maintenance costs. The design can move the required distance of 150m as shown in the figure 1. The push mechanism applied uses the force of 20 to 50 newton. Thus, based on the analysis provided above, design A was better than B and C based on the detailed solution analysis of the designs given. 5.0. References Chryssolouris, G., 2005.
