A force Q is directed from a point A(4,1,4) meters towards a point B (-3,4,1) metres.Determine the moment of force P about x and y axis if it produces a moment of 1000Nm about z axis.

The 20-kg slender rod is pinned at O. For the moment the cable attached at the

end A suddenly breaks, you are asked to

(a) provide forces (free body diagram) and motion analysis

(b) determine the acceleration of the end A

(c) find out the reaction at the pin support.

Determine the shear and moment as a function of x, and then draw the shear and moment diagrams.

 A hollow shaft has an inner diameter of 0.035 m and outer diameter of 0.06 m. Determine the polar moment of inertia of the hollow shaft.
