Question

QUESTION 2 The bolted connection shown in Figure 2 below is connected with 3/4-in-diameter bolts in standard holes. The plate material is A36 steel. Find, using strength level design (LRFD), the available tensile strength of the plates. Figure 2

can someone help me with this structural design II QUESTION
