## Homework Statement

Solid slab with moment of inertia 2 kg m

^{2}is given the forces as shown.

Find the angular acceleration if θ = 37°, R1 = 10 cm, R2 = 25 cm

## Homework Equations

τ = I . α

## The Attempt at a Solution

This is what I've tried although I don't know it is correct or wrong; I tried to find all the torques by the 4 forces.

τ

_{1}= 10 x R2 (clockwise)

τ

_{2}= 10 x R1 (anti-clockwise)

τ

_{3}= 20 x R1 (anti-clockwise)

I can't find the fourth torque because I don't know how to find the perpendicular distance from the inclined-10 N force to the center. Please help

Thanks
