Chapter 4, Problem 104P

Please help.

If the resultant force of the loads passes through point B, find the equivalent force-couple system (moment) at point O

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.

Replace the loading acting on the frame by an equivalent resultant force and couple moment acting at point A. 80 lb 60 lb 3 ft 3 ft- 3 ft 3 ft B A 2 ft + 4 ft 75 lb 40 lb

Handle forces F1 and F2 are applied to the electric drill. Replace this force system by an equivalent resultant force and couple moment acting at point O. Express the results in Cartesian vector from. Determine the resultant force and the moment of the resultant forse about the point O. Express your answer in terms of the unit vectors i, j and k.

Find the moment about point A resulting from the force of the knee on the helmet, as shown. Also, find the force F at the base of the neck needed to resist this moment.

Q3: Replace the force system acting on the frame by an equivalent resultant force and couple moment acting at point 4. Take F- 1500 N 500 N 05m -03m-

Replace the loading by an equivalent resultant force and couple moment at point B.

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
