Solid slab with moment of inertia 2 kg m2 is given the forces as shown.
Find the angular acceleration if θ = 37°, R1 = 10 cm, R2 = 25 cm
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.
τ1 = 10 x R2 (clockwise)
τ2 = 10 x R1 (anti-clockwise)
τ3 = 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
