Compound lever shears cut through a piece of wire at A (Figure P5.32).

(a) By using the free body diagram of handle CD, determine the magnitude of the force at rivet D.

(b) Referring to the magnifi ed cross-sectional drawing of the connection at D, determine the shear stress in the rivet.

(c) If the rivet is formed from 4340 steel alloy, what is the factor of safety?
