## Homework Statement

A force of magnitude 50N is applied at the bottom point Q of a disk of radius 8m that is pinned at P

(leftmost point)

See attached picture

(a) Find the angle between the force and the vector from P to Q.

(b) Find the magnitude of the applied torque.

## Homework Equations

|T| = |F|sin(Theta)*|r|[/B]

## The Attempt at a Solution

So for part (a) I said the angle was 85 degrees but apparently that's wrong? At least according to my colleges online homework program. honestly don't know how to start part (b)
