The bolted connection illustrated below comprises one bolt and two plates. The bolt, which has a diameter of 20 mm, is threaded through a 22- mm diameter hole in both plates. The shear stress of the bolt is 78,000 MPa. Based on this information, determine the following What is the largest force F that can be placed on the joint without shearing the bolt? what is the normal stress, at the gross section area, in each plate? what is the normal stress, at the net section area, in each plate? what is the bearing (or contact) stress between the bolt and each plate?

A steel truss structure is loaded as shown in Fig. 1. The truss members are made of A36 steel (f, = 36 ksi). All the members are made up of two 3.0"x5.0" (each) parallel flat bars. All the joints have bolt connection (pin connection), acting in double shear. The diameter of all the bolts is 3.0". Determine, •The average normal and shear stresses in bars AB, and Cl and the shear stress in pin H. •The average normal and shear strain in AB, and CI and shear strain in pin H (Given, E = 29x106 psi, G = 11x 106 psi) 4k 4k C IH or GH 8 ft A Pin H JT H 4k 6 @ 8 ft = 48 ft Fig. 1
