Answer:
τ = 34.5 N.m
Step-by-step explanation:
The force applied by the mechanic is 230 N.
Thus, F = 230 N
Now, this force is applied in a counterclockwise manner while pushing perpendicularly at the end of the 0.15m long wrench.
Thus, r = 0.15 m
Formula for the torque in this case is;
τ = Fr sin θ
θ = 90° since mechanic pushed perpendicularly.
Thus;
τ = 230 × 0.15 × sin 90
τ = 34.5 N.m
