Chapter 4, Problem 42P

Find the sum of the moments of the two forces O about the point F and P

Determine the resultant moment produced by the forces FB and FC about point O. Express the result in vector notation and obtain its magnitude.

Determine the moment of the force F about point O. Express the result as a Cartesian vector. Find the magnitude of the force. (Note F=132N)

The crowbar is subjected to a vertical force of P = 27 lb at the grip, whereas it takes a force of F = 160 lb at the claw to pull the nail out. The crowbar contacts the board at point A. Find the moment of the force P about point A and the moment of the force F about point A.

Determine the moment of the force F about point P. Express the result as a Cartesian vector.

The pipe assembly is subjected to three forces of F1 = {3.00, 4.00, -2.00} kip, F2 = {0, 0,-4.00} kip, and F3 = {-3.00, 0, 0} kip. Determine the sum of the moment of the forces 1) about x-axis (the unit vector of x is i) and 2) about line AC. Express the result as a Cartesian vector.

Two men exert forces of P- 50lb and F= 80 Ib on the ropes. Determine the moment of each force about A. Which way will the pole rotate, * ?clockwise or counterclockwise

The towline exerts a force of P= 4 kN at the end of the 20-m-long crane boom What is the magnitude of the maximum moment about point O? Is the direction clockwise or counterclockwise? If θ = 32 ∘ , determine the placement x of the hook at A so that force P creates a maximum moment about point O.

Determine the moment of the force about point O.
