The uniform crate of mass M is suspended by using a cord of length l that is attached to the sides of the crate and passes over the small pulley at O. If the cord can be attached at either points A and B, or C and D, determine which attachment produces the least amount of tension in the cord and specify the cord tension in this case.
Given:
M = 50 kg
g = 9.81 m/s2
a = 0.6 m
b = 1.5 m
l = 2 m
c = a/2
d = b/2
