Why I calculated it and it's -210 not 210?

And yeah thx a lot❤

This calculates the magnitude of the moment about the origin; to compute the moment about the Y-axis you must take (r x F) where vector r is <0, -3, 2> the x value should not be included in the radius vector to solve for the moment about the Y-axis.

It is equal to +90, not 210 or -90 !!!!


But anyway you are the best👌😍

Why its positive 150? (50)(-3)(1)= -150 right? So 60-150= -90
