What is the torque on a bolt applied with a wrench that has a lever arm of 30 cm with a force of 30 N?

The torque on a bolt will be "9 Nm".

Given values are:

Force applied,

Lever arm,

As we know the formula,

→

By substituting the values, we get

→    

→    

Thus the above response is correct.

9 Nm

Explanation:

The formula for torque is;

τ = lever arm * force applied

τ = 30/100 * 30

τ = 9 Nm

what is the actual question though?

because if the tool that you are using is not balanced it there would be false mass.
