The force, $F=(8i+13j+-22k)lb,$ is attached at the end of a bent pipe at point, $(-21ft,30ft,40ft)$ and the

height of the vertical section is $24$ ft $.$ Also, a moment, $M=262ft-lb,$ is applied around the z axis in the

direction shown.

b$.$ What is the position vector that is used for

calculating the moment from the force, F $,$

around point $O?$

c$.$ What is the moment caused by the force F

around point O $?$

d$.$ What is the total moment created around the origin $($point O $)$ from the force, F $,$ and moment, M $,$
