Find the moment of the 450N force F, about point A, from the following
pipe, knowing that the pipe starts from point A (embedment). NOTE:
we are working with a pressure of 0.1 N.m

not your homework board. It's a simple geometry problem to calculate the position vector and then take the dot product.

Moments are defined as the cross product of the lever arm vector with the force vector, AKA r x F, AKA arr cross eff.

The lever arm is <3, 1.2, -2.4> meters, but I'm too lazy to project the force vector onto those vector components and take the dot product. You do the rest.

CROSS product, not dot product. Don't let anyone tell you differently.
