A utility crane as shown in the simplified schematic layout, is to be constructed in an automotive repair facility to raise heavy loads. It is comprised of four primary load-carrying members labeled 1, 2, 3, and 4 as shown. These members are connected to each other with pin-type joints at $$A$$, $$B,C,D,E,F$$ and G. Anchor points is provided at points A\& B that carry the loads from the crane's boom to a rigid structure. Assuming that all members are rectangular shape with allowable stresses as follows: 1. Analyze the forces that are exerted on each load carrying member using the principle of statics 2. Identify the kinds of stresses that each member is subjected to base on the applied forces 3. Design diameter of pins and; 4. Find the dimensions of load carrying member
