0.372m
0.345m
0.425m
0.375m
Solution:
Step 1: Recall the torque equation T = F * r, where T is torque, F is force, and r is the length of the wrench. Step 2: Rearrange the equation to solve for r: r = T / F. Step 3: Plug in the given values: T = 15Nm, F = 40N. Step 4: Calculate r: r = 15Nm / 40N = 0.375m.
