Chapter 4, Problem 75P

If F1 = 100 N , F2 = 120 N and F3 = 80 N, determine the magnitude and coordinate direction angles of the resultant couple moment.

*Determine the magnitude of the moments of the force F about the x, y, and z axes.* Pt A. Solve the problem using a Cartesian vector approach. Pt B. Solve the problem using a scalar approach.

4. The wrench is subjected to the 200-N force and the force P as shown. If the equivalent of the two forces is a force R at O and a couple expressed as the vector M = 20k N m, determine the vector expressions for P and R. 300 mm 200 N 160 mm Ans. P = 40j N R = -160j N

The equivalent resultant force acting on the beam is zero and the resultant couple moment is 7 kN⋅m clockwise. Determine the position a of the triangular load on the beam.

Two couples act on the beam. Determine themagnitude of F so that the resultant couple moment is450 lb ⋅ ft, counterclockwise. Where on the beam does theresultant couple moment act?

The magnitude of force P is 480N. Determine the moment of P about the axis CD. Express the result in vector form.

For the given loading system, find the equivalent resultant force and couple moment acting at point B. 50 lb/ft 100 lb/ft 50 lb/ft 6 ft 4 ft

Replace the two forces with an equivalent resultant force and couple moment at point O. Let F = 20 lb.

The ends of the triangular plate are subjected to three couples. Determine the magnitude of the force F so that the resultant couple moment is 400 N m clockwise. 600 N 600 N 40° 40° 1 m 250 N 250 N
