Take F=260 lb. Determine the normal force, shear force and moment acting at sections passing through point C on the curved rod.

(a) Replace the force F=2800i+1600j+3000klb acting at end A of the crank handle with a force R acting at O and a couple-vector CR. (b) Resolve R into the normal component P (normal to the cross section of the shaft) and the shear component V (in the plane of the cross section). (c) Resolve CR into the twisting component T and the bending component M.

Determine the moment at point O due to the application of the 25 N force. FB =18 N Fp =25 N 8 m 10 m 2 m 3 m- - 6 m.
