A wrench with a length of #20 cm# is being used to unscrew a #4/3 cm# bolt. If a torque of #5 Nm# is needed to overcome the friction keeping the bolt in place, what is the minimum torque that must be applied to the wrench to unscrew the bolt?

A torque of 5Nm will unscrew the bolt.
Explanation:
It seems that some information might be missing or entered incorrectly.
However, it says that a torque of 5Nm is needed to overcome the friction keeping the bolt in place. Overcoming friction is all that is needed to unscrew the bolt.
I hope this helps,
Steve
