Requirement definition 1.0. Introduction For this project‚ the aim was to research different geared trolley cranes and come up with a brief outline/ design which would meet some specific design limitations. The trolley crane that we had to come up with was meant to be designed to lift and carry a load of 1.5 tonnes along I-beam of 4 metres long. The research that we did was mainly on existing trolley cranes and the configurations of these cranes which allowed us to familiarize ourselves

Fluid Report 2 In the derivation of Bernoulli’s equation‚ the assumption of the inviscid and incompressible flow is used. However in the real case‚ the viscosity cannot be neglect and the density of the flow is not always constant. Thus Bernoulli’s equation is not always correct. For the lab‚ it is reasonable to assume the flow is inviscid and incompressible. Firstly‚ the pitot was placed at the center of the flow. The skin friction (effect of viscosity) is inversely proportional to distance

What is the total angle of twist at the free end‚ if maximum shear stress in the shaft is limited to 83 Mpa for steel and 55 Mpa for aluminum? Assume the modulus of rigidity to be 83x1000 N/mm2 for steel and 28x1000 N/mm2 for aluminum. 5 Q2. (a) What is effective length of a column and slenderness

WHAT IS FLUID MECHANICS ? FLUIED: Any thing whose particles can move easily from one place to another that means shape can be easily changed upon the application of negligible force. MECHANICS: Study of response of bodies upon the application of force. FLUID MECHANICS : Fluid mechanics may be defined as the branch of engineering science which deal with behavior of fluids under the condition of rest and

make the fat particles small enough to mix together with the watery components of the coconut milk. The samples of coconut milk subjected to higher pressure show a higher temperature with longer time interval‚ this is due to mechanical friction and shear force in the homogeniser. During this experiment a major precaution which had to be taken was not to allow the feed tank in the homogeniser to run out of liquid as this will cause a malfunction and would spoil the machine.

COMPOSITES COURSEWORK DESIGN AND ANALYSIS OF A LAMINATED COMPOSITE TUBE ABSTRACT This report details the process for the design of a composite laminate tube‚ the software package ’MathCAD’ was used to determine a lamina design with a configuration that avoids mechanical failure under loading conditions. It was also used to obtain twist angles and maximum stresses for specific lamina wind up angles. The report will provide analysis of the methods used to obtain these criteria. AIM Use a Mathcad
