Explanation / Answer
a) Torque due to F2 will be largest
b) Torque due to F6 will be smallest
C) Torque due to F1. F1xcos30xd =0.866F1d
d) torque due to F2 = F2 ×2d=2F2d
e) torque due to F3 =[F3cos60]×3d=1.5F3d
f) torque due to F4 = F4 x d
g) torque due to F5 =F5 cos45×2d =1.41F5 d
h) torque due to F6 = F6 X0 = 0
