Question

Find the moment about the y-axis

Answer 1

The vector that points perpendicularly away from the axis of rotation to the point of contact is <0, 2, 0> and the force vector is < 30, -20, 15>.
\[\vec{r} \times \vec{F} = ? \]

Answer 2

Which point of contact are you referring to?
axis of rotation is y.

For perpendicular line from y-axis to line of force I have \[\vec{r}=<-4,-3,2>\]
