Chapter 4, Problem 75P

Determine the coordinate direction angles of the force F applied at the end of the pipe such that the moment of F about point A is zero.

Determine the x and y components of the resultant force and the resultant couple moment at point O. 500 N + 2m 100 N 500 N

Determine the moment of the 80-lb force about the Oa axis. Express the result as a Cartesian vector. C 5 ft 30° 4 ft B 30° 45° 80 lb 6 ft 60° 120°

1. Aforce F is applied to the wrench. Determine the moment of this force about point 0. Solve the problem using both a scalar analysis and a vector analysis.

3. Replace the two forces acting on the post by a resultant force and couple moment at point O. Express the results in Cartesian vector form. C FB=5 kN Fp =7 kN 6 m 8m 2 m 3 m. 6 m.

If the couple moment has a magnitude of 300 lb-ft, determine the magnitude of F of the couple forces 12 ft -F 7 ft 2 ft 1 ft 6ft F -12 ft-
