1. A single-bolted double-cover butt joint is used to connect two plates which are 8 mm thick. ssuming 16 mm diameter bolts of grade 4.6 and cover plates to be 6 mm thick, calculate the rength and efficiency of the joint , if 4 bolts are provided in the bolt line at a pitch of 45 mm s shown in Figure 1. Also, determine the efficiency of the joint if two lines of bolts with two olts in each line have been arranged to result in a double bolted double cover butt joint.
