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,
