MM←ⒸOD=1175 mmⒸ Homework ProblemYou are tasked to check the safety factors for the bolt designs for the connection shown with anarrow below. The relevant dimensions are as follows. Bolts: 24 x M48 Coarse-Pitch, Grade 8.8steel; (use textbook values for M36 strengths). Nut height H = 38mm; Washer height 8mm. Steel:Grade 1050HR steel; top plate thickness = 75mm; bottom plate thickness = 50mm. Appliedmoment M = 4016 kN.m. Assume that the connection is permanent. Also calculate the requiredtorque to bring the bolts to the correct pre-tension. (All surfaces are zinc-plated).955ESS 0000DFor this assignment assume that the load on any bolt is F = Fmax sin 0. Where is defined asbelow and where Fmax is the maximum force of any bolt. Sum the moments due to all the bolts,and thus estimate the largest bolt load.
