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

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.

you have been hired to design a family-friendly seesaw

rom the end of the board when seated. You have selected a child of mass,  (seated furthest from the pivot) and an adult of mass, (seated closest to the pivot) to test out your prototype.

a. Determine the distance d in meters.

b. Determine the magnitude of the force exerted on the pivot point by the see-saw while in use in newtons.

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.
