Question #172819

A circular metal plate with radius 0.22 m. Calculate the net torque about O given that F_{1} = 17.4 N, F_{2} = 7.2 N, F_{3} = 14 N, F4 = 5.4 N, θ_{1} = 58°, and θ_{2} = 38°.

Expert's answer

"F_2\\cdot\\sin38\u00b0\\cdot0.22-F_1\\cdot\\sin58\u00b0\\cdot0.22+F_4\\cdot0+F_3\\cdot0.22="

"=7.2\\cdot\\sin38\u00b0\\cdot0.22-17.4\\cdot\\sin58\u00b0\\cdot0.22+"

"+5.4\\cdot0+14\\cdot0.22=0.81\\ (N\\cdot m)" clockwise . ** Answer**
