Chapter 4, Problem 76P

Determine the required magnitude of force F if the resultant couple moment on the frame is 250 Ib.ft clockwise -2 ft-2 30° 2 ft 150 Ib 150 lb 2 t 30 2 ft

If F = 300KN, determine the resultant couple moment. -2 m 2m F 30° 2 m 250 kNA 250 kN 2 m 30° 3. 2m

The 60-N force acts at point A on the lever as shown. Replace the force at A by a force and couple moment acting at point 0 that will have an equivalent effect. 60 60 N 200 mm

Q1: The 100-N force is applied as shown to one end of the curved wrench. If a = 55°, calculate the moment of F about the center O of the bolt. F=100N -A 70 mm 25 mm 150M 70 mm 25 mm

Current Attempt in Progress The 4.0-lb force is applied at point A of the crank assembly. Determine the moment of this force about point O. F = 4.0 lb 22 0.60" -y 2.10". Answer: Mo =( i i+ i j+ i k) Ib-in.
