Extract of sample "F0RCE, TORQUE, AND EQUILIBRIUM"

Download file to see previous pages This experiment entails the measurement of the forces that are applied on an object. The object under consideration in this case is the equal arm balance. The torque created by individual forces will be computed and then we will show that the computed net torque is zero.
1. To compute torque due to individual force applied to the Equal Arm Balance at diverse positions in diverse directions, it is requisite to establish the direction of a vector, which is drawn from the axis. This brings us to the determination of the angle between r and F, which is given by the following equation
4. Link the force sensor to a Go-Link. Then plug it into the computer. Double click on Force and torque. This will facilitate opening of the LoggerPro Program. The program will be used to read and show the force sensor senor data.
The fact that the net sum of vector torques adds up to zero confirms that at the point of equilibrium the object is not in directional movement that can lead to change in magnitude of distance but it is constrained to move in a rotational manner due to the fulfillment of the above two principles under investigation (net force equals zero and net vector sum of torque equals zero). In this regard, the principle of Isaac Newton’s force of gravity and centripetal acceleration are fundamentally essential to note. Hence the experiment affirms the fulfillment of the second condition of equilibrium.
The science that is behind the functionality of the human arm is immensely attributed to the movement of the muscles which result to a motion supported by the biceps and the triceps of the arm. This section, will offer an opportunity for measuring the forces attributed to the biceps for holding a weight on the hand at 90 degrees. Computation of the torque due to this force comparative to the weight model that the arm holds will be done.
1. The force sensor should be fastened on the vertical rod just right on top of the arm model. Then one end of the cord attached ...Download file to see next pagesRead More

Market equilibrium

According to the law of demand, an increase in the price of a product causes a downward movement along the demand curve leading to an increase in the quantity demanded whereas a decrease in the price causes an upward movement along the curve causing a decrease in the quantity demanded (Lipsey, & Chrystal, 2001). A change in demand occurs when the demand curve shifts due to changes in demand determinants such as income, buyer preferences, expectations, prices of other goods, etc (Hobday, 1999). Law of supply states that as the price of a product rises, keeping all other factors constant, one would be willing to supply more for sale. Hence, price and quantity supplied are positively related (McConell, Brue, & Flynn, 2009). Economic...

Supply, Demand, & Equilibrium

... 04 July 2008 Supply, Demand, and Equilibrium The wage of a worker as with the price of goods in the market is determined by supply and demand. It should be noted that in the labor market, as with the goods market, some workers are “valued” higher than the others thus demanding the payment of higher wages compared to the employees in other profession. Using real world example, professional sports players are paid much higher than farmers, factory workers, engineers, and teachers even though all of them are generally in competitive markets. In order to assess this situation, this paper will conduct an analysis using the diagram of supply and demand. In the first case, it will look at farmers, factory workers, engineers, and teachers...

Static Equilibrium

Static equilibrium Static equilibrium con s the in which the particles of an object are at rest orstationary. Static equilibrium is when the sum total of the forces acting upon each individual particle is equivalent to zero (Herbert 133) An object is considered to be in equilibrium when the sum total amount of force acting upon it is balanced. This condition may not necessarily insinuate that the forces acting upon it are equal. Therefore, the total amount of force of the object is zero (0m/s/s).
Objects in a state of equilibrium have an acceleration of 0m/s/s, this emanates from the Newton’s law of motion. An object with zero acceleration does not imply that, it is at rest. Objects in equilibrium state are at rest and stayin...

Market equilibrium

...Market Equilibrium Law of demand and the determinants of demand The law of demand s that if the prices of commodities are high, then buyers of commodities will inquire lower quantities compared to the case when the prices are low. It is obvious that a decrease in price will lead to demand for large quantities (Lieberman & Hall, 2008). Demand has several determinants such as income, tastes and likes, price of associated commodities, populace and others. If we consider the demand of homes in the market, income is a determinant since it lowers or increases demand for the commodity. High population will increase demand while the tastes and preference will affect the choice of the commodity (Lieberman & Hall, 2008). Law of supply...

... Equilibrium A market is said to be at equilibrium when the supply of a good is equal to the demand of the good mostlyattained when there is neither shortages nor surpluses in the market, thus, making prices to remain stable (Chiappori and Ekeland 2006). With the recent health reports, the firms in the industry will maximizes its profits in the short run while they cannot make bigger profits through alteration of the prices of milk, thus, in the short run, the firm may make super-normal profits. In the short-run, the firms will not necessarily need to make profits or cover all its costs; it may only need to cover the total variable costs incurred thus the rising cost of milking equipment will not have any effect on the firms... Equilibrium A...

... Equilibrium It is apparent that producers with an understanding of price elasti will always be in a position to predict the effects of price changes in regard to total revenue. In case there is a price hike, producers will be sure that each unit of the good sold will sell for a higher price (Stretton 22). This translates to raising revenue. This is what is termed as price effect. On the other hand, after a price increase, in another dimension, it could also mean fewer units of the goods will be sold. This has the effect of lowering revenue. Price elasticity gives an overview of effect on quantity and price for each unit. Additionally, price elasticity revolves around demand of the product. When demand is inelastic, it is apparent...

Moment and equilibrium

... Moment and Equilibrium Introduction An object is in balance when it has no trend to turn or change, that is no conversion and no spinning .When a figure is in equilibrium the anticlockwise moments round a point is equivalent and contradictory to the totality of the anticlockwise moments about that point and likewise the resulting force is zero (Lee, 2010).. This is presented by the demonstrations chosen some loaded beams. Moment of force therefore is that force that is due to the revolving effect ,for example when a force is subjected to one end of an body whose other end is attached to a pivot , that pull or push will tend to revolve the object about the pivot thus that turning effect obtained is the moment of force. Aim The aim...

Static Equilibrium

From Newtons 1st law, an object is in equilibrium when it moves at constant velocity (Mathew, 2010, pp5). Static equilibrium is thus a system at rest is said to be in static equilibrium. The summation of equilibrium forces in each direction adds to zero. Also, the total net summation of torque is equates to zero. (Mathew, 2004, p.3).ԐFx=0, ԐFy=0, ԐFz=0, ԐԎ=0,Fx becomes the force that occur in the X direction and Fy are the forces that occur in the Y component direction (Mathew,2010.pp.7). Fz is the force acting towards the Z direction. Force in an action as either a push or a pull that acts on an object. It has units given Newton. (N). Torque can be defined as the product as force and distance (r) about a point that causes the obj...

... Equilibrium Fujita and Nuimura (14011-14014) present in their article the results of estimation of changes in three benchmark glaciers in the Nepal Himalayas. The energy-mass balance model was used for the analysis of the processes, which affect the shrinkage of glaciers. This approach includes calculation of the radiance balance (heat fluxes, heat conduction) and mass balance (freezing, snow accumulation, melt, evaporation) for the three chosen glaciers in Nepal. It was found that the glaciers in the humid areas show the increased mass wastage comparing 1970-1990s. The glacier in the arid areas shows the suppression of mass wastage in the last decade. Apart from mass balance and energy balance, the analysis of equilibrium line altitude...
