Chapter 13 349 The shear forces are independent of the rotational sense. The bolt tensions and the shear forces for cw rotation are, Tension (lbf) Shear (lbf) A 0 145 B 0 145 C 1109 300 D 1109 300 For ccw rotation, Tension (lbf) Shear (lbf) A 182 145 B 182 145 C 0 300 D 0 300 13-33 T in = 63 025 H / n = 63 025(2 . 5) / 240 = 656 . 5 lbf · in W t = T / r = 656 . 5 / 2 = 328 . 3 lbf γ = tan 1 (2 / 4) = 26 . 565° = tan 1 (4 / 2) = 63 . 435° a = 2 + (1 . 5 cos 26 . 565°) / 2 = 2 . 67 in W r = 328 . 3 tan 20° cos 26 . 565° = 106 . 9 lbf W a = 328 . 3 tan 20° sin 26 . 565° = 53 . 4 lbf W = 106 . 9 i 53 . 4 j + 328 . 3 k lbf R AG = − 2 i + 5 . 17 j , R AB = 2 . 5 j M 4 = R AG × W + R AB × F B + T = 0 Solving gives R AB × F
