Question

The towline exerts a force of p = 4 kn at the end of the 20-m-long crane boom. if u = 30, determine the placement x of the hook at a so that this force creates a maximum moment about point o . what is this moment?

Answer 1

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)
