Final answer:
The minimum length wrench required is 0.140 meters.
Step-by-step explanation:
To find the minimum length wrench, we need to use the torque formula:
Torque = Force x Distance
Given that the machine is only capable of applying a force of 200N, we can calculate the minimum length wrench by rearranging the formula:
Length = Torque / Force
Substituting the values:
Length = (200N x 0.140m) / 200N = 0.140m
Therefore, the minimum length wrench would be 0.140 meters.
