Question 1 The figure below is a simplified sketch of the mechanism used to raise the bucket of a bulldozer. The bucket and its contents weigh 10 kN and have a centre of gravity located at point H. The arm ABCD has a weight of 2 kN and a centre of gravity located at B; arm DEFG has a weight of 1 kN and a centre of gravity located at E (the weight of the hydraulic cylinders can be ignored). The arm of the hydraulic cylinders CJ is to be made out Stainless 304 steel and all the connecting pins are to be made using A-36 steel. Connecting pins A, D, G and I work as double shear connections. Connecting pins B, C, E and F work as single shear connections. You are required to: a) Calculate to the nearest multiple of 5 mm, the diameter of the hydraulic cylinder arm CJ (use F.S.-4). b) Calculate, to the nearest multiple of 5 mm, the diameter of pin A (use F.S.=2).
