Torque : Example Question #1
A bolt connecting the main and rear frame of a mountain bike requires a torque of 15N⋅m to tighten. If you are capable of applying 40N of force to a wrench in any given direction, what is the minimum length of the wrench that will result in the required torque?
Possible Answers:
0.84m
0.21m
0.38m
0.60m
0.33m
Correct answer:
0.38m
Explanation:
The minimum length of the wrench will assume that the maximum force is applied at an angle of 90∘. Therefore, we can use the simplified expression for torque:
T=F⋅r
Here, r is the length of the wrench.
Rearranging for length and plugging in our values, we get:
r=TF=15N⋅m40N=0.375m
