Problem 1: Determine the maximum normal stress at section a-a. The cross-sectional area is a square. Draw the FBD. 10 N 20 kN P 50 N 0.1 m 22mm 0.5 m 60 mm 100 mm Problem 2: If the 60-mm diameter shaft is subjected to an axial force of 20 kN, determine the average shear stress developed in the shear plane where the collar A and shaft are connected. Draw the FBD. 15 mm a -0.3 m O 2.5mm 2.5 mm Problem 3: The lap joint is fastened with four 20-mm diameter rivets. The working stresses are 100 MPa for the rivets in shear and 125 MPa for the plates in bearing. Find the maximum safe axial load P that can be applied to the joint. Assume that the load is equally distributed among the rivets. Draw the FBD. 100mm ↓ σ= 22mm ✓ P T= Answer P = Answer Answer
