I. Bolt Calculation (Shear)     Assumptions : 1. Maximum applied load = 800 lb (3558.4 N)   2. Torque applied of each bolt : New =  410 lb.ft     Old = 630 lb.ft   3. External forces acting on each bolt are static.  1.     2. 3.      Since all the radius is the same, Force on each bolt 4.  (r)     Free Body Diagram

5. The distance from the centroid to the center of each bolt  Ra = Rb = Rc = Rd = Re = 145 mm   6. Primary shear load per bold       7. Secondary shear force diagram        Assume bolt did not move
8.                       All bolts are critical because they carry the same amount of shear load Diameter of the bolt = 1.125 inch ( 29mm) 9. Pitch diameter of the bolt       Pitch of the bolt, p = 7 threads per total length of the bolt (68mm)
