There are 2 defective batteries and 10 good batteries.
a) none of the defective batteries (10C3) = 120
b) one of the defective batteries (10C2)(2C1) = 90
Answer:
The answer is 80 kN . m (clockwise)
Explanation:
As,
M = P x L
Here, the towline exerts a force is P.
Substituting P for 4000N.
M = -4000N x 20m
= -80000N.m
= 80kN.m
Maximum moment about the point O is 80kN.m (Clockwise)
