The soft-ride suspension system of the mountain bike is pinned at C and supported by the shock absorber BD. The seat is designed to support a load of P-1500 N. Pin B attaches the shock absorber BD to the suspension system, has a diameter of 7.5 mm, is made of a material having a shear failure stress of trals 150 MPa and is subjected to double shear. a) Draw a Free Body Diagram of ABC (the combined seat and soft-ride suspension system) (2 Marks) b) Determine the factor of safety against failure of pin B (8 Marks).
