1 In a cylinder of bore (d) 80 mm the
maximum pressure exerts a force (F) of 14000 N on its top head. The cover
plate is secured by (n) 6 bolts. Determine: 

2 Determine the safe tensile, shear and bearing loads and the efficiency for a 200 mm section of singleriveted lap joint made from 6 mm plates using four 16mm diameter rivets. Assume that the drilled holes are 1.5 mm larger in diameter than the rivets. The values for the design limits for tensile, shear and bearing stress can be taken as 75, 60 and 131 MPa, respectively.





3 Find the equations of stresses at point A due to a force F. The pin diameter is d.


4 Define the following:
a Stress, b Types of Rivets, c Types Rivets joints
