Therefore, manufacturer must be in a position to appreciating these differences to avoid the production of plastic materials and products with premature failures commonly referred to as nasty and cheap.
The plastic containers adopt the pseudo-elastic design methodology, which involves substitution of appropriate Poisson’s ratio and values of Modulus (that depend on temperature and appropriate time). The substitution involves using elastic standardised strain solutions, which depends on the geometry of the part and the load configuration. The method is appropriate for experimenting and investigating the design failures for polypropylene tanks. Some of the successful approach involve analysing the stress to the 4th order of the linear differentiation (Lewis and Weidmann, 1999a; Lewis and Weidmann, 1999b). The equation takes into consideration the transition between the vertical and the horizontal dimensions as well as the thickness. The manifestations of these transitions are accounted when the wall of the tank increases through radial expansion. The phenomenon can be described as stress concentration.
The method involve assessing the strength parameters based on general values like stability (buckling, kinking), deformation (excessive bends), and strain or stress. Most failed tanks will fail at the welded construction at the joint level. Therefore, the best approach is to adopt a limiting stress criteria, which will aim to provide conservative alternatives to the problem (Lewis and Weidmann, 1999a; Lewis and Weidmann, 1999b).
The design of the tank is very important. The hydrostatic pressure increases linearly and proportionally with the tank’s height. This means that the most appropriate strategy of resisting the pressure is by increasing the tank thickness. The same principle is applicable when constructing the walls ...Download file to see next pagesRead More

Mechanical Dynamic
...? Mechanical Dynamic Mechanical Dynamic In the world today where technology has advanced and world has become a global village, thereis also a lot of pressure on the automotive industry, pressure of inflation, consumer action, oil crisis and majorly government regulations. Product requirement is that it is a light weight product which is reliable and efficient. Corporate social responsibility is also a very important factor here as per which noise pollution needs to be avoided the maximum they can and also less vibrations are required. Designers now face a higher challenge of product development and thus they require better tools and equipment for testing. Mechanical dynamics is one...

...mechanisms of the technique as well as the functions, properties and experimental setup (Sullivan & Liu 2004). This technique has been found to be easier, more accurate faster and cost effective as compared to the use of pressure ports and computational fluid dynamics for external pressure management. The traditional pressure measurement methods would take at least one week to obtain the results while the pressure sensitive paint technique takes 15 minutes only to produce reliable results which include a the global surface pressure measurements. It is also easier as it does not require one to drill pressure ports or wait for the computer to process numbers as in the cases for use of pressure ports and computational fluid...

...?Mechanical Engineering- Mechanical Project Materials remain the fundamental components utilised in construction of engineering structures. In the development process, the structural requirements remain essential in assisting developers into deciding on the correct materials for use within different structures. Making material choice remains an essential element for enhancing proper functioning of the structure, upon construction. The selection process for materials follows analysis of the functions for the proposed structure being constructed. The functions determine the required material strength among other properties; hence selection of material meeting structural requirements (Jones 1975). Other than strength and stiffness... . The...

Mechanical properties and acoustic behaviour of screed
...mechanical properties and acoustic behaviour of screed Screed definition All residential, commercial or industrial buildings use screed to provide smooth and flat floor. Apart from this, it can be used to increase the structural strength of the base floor slab while increasing the depth of the slab as well. Screed is a well defined mixture of cement and fine aggregate, called soft concrete, which when mixed forms a layer of compact material. This is applied to the surface base in the specified thickness and for providing a surface finish for the receiving floor or roof/ ceiling. It can be used as a topping to provide dense concrete base for improving the structural depth and strength of the base. The...

...Task The condition of flow (laminar, transitional or turbulent) in a pipe due to frictional effects can be determined by knowing the Reynolds number. Reynolds number is a dimensionless quantity (Ratio of dynamic force to the viscous force) that helps to classify flow. Reynolds number for a given pipe diameter D is given by Red = Vave D ρ / υ ….. (1) Where Vave is the velocity of the flow, ρ is density of the fluid and υ is the kinematic viscosity of the fluid. Generally the laminar flow corresponding to Red ≤ 2100, transient occur in the range of 2100 4000 and turbulent flow is for Red ≥ 4000. Now in order to calculate Reynolds number we would use a head orifice flow meter. The arrangement of controlled water supply... The condition of ...

...Mechanical Engineering Introduction Mechanical engineering is a broad that derives its scope from the necessity to manufacture and design everything from large systems (such as machine tools and spacecraft) to small devices and individual parts (such as Inkjet printer nozzles and micro scale sensors). The function of the mechanical engineer is to design a product from an idea and take it to the marketplace. In order to finish this, a number of skills are required. The mechanical engineer is required to acquire certain knowledge and skills. He is needed to understand the thermal environment and forces that a product, its subsystems, or its parts will meet (Columbia University 1; U.S. Bureau of Labor Statistics 1; America Society... of...
