A wrench 0.6 meters long lies along the positive y-axis, and grips a bolt at the origin.

A force is applied in the direction of ⟨0,4,4⟩ at the end of the wrench.

Find the magnitude of the force in Newtons needed to supply 100 Newton-Meters of torque to the bolt.

Step 1

Refer to the question, To find the toque use the formula T= r * F, where r is the vector drawn from the bolt to the point where F is applied.

Step 2

As |r| is the length of the wrench, as the force is applied at the end of the wrench.

Step 3

We know that the wrench lies along the positive y-axis and it is given that F lies along the v...
