Answer:
The resultant torque on the body is 10 N·m in clockwise direction (-k).
Explanation:
Formula for torque is τ = r × F
where r is perpendicular distance between center and point of application of Force.
Hence, resultant torque
τ = (5×50) + (4×30) - (1×20) - (3×80) (-k)
τ = 150 + 120 - 20 - 240 (-k)
τ = 10 (-k) N·m
