COMPUTER AIDED ENGINEERING

STRUCTURAL ANALYSIS BY COMPUTER AIDED ENGINEERING METHOD USING FEA APPLICATION

Design an engine crane/hoist as similar to crane shown in Figure 1 below. The design must consist of all the elements, components and parts as in Figure 1 below. Design of the structure is crucial in order to withstand the weight of the engine.

Other specification are as follow;

1)      Total length to be less than 1.5m

2)      Total height to be between 1.9m to 2.0m

3)      Boom can extend about 2.0m in total

4)      Able to lift engine ranging from 2.0L to 3.0L engine capacity
