2. Using a wrench to tighten a bolt creates an effect called a torque, which is a vector 7that lies on the axis of rotation of the bolt. To be more precise, torque is defined as the cross product F=ix, where is the vector directed along the wrench and terminating at the point where force is being applied, and where is the force vector. See the image below. T = r *F. Suppose a wrench that is 40 cm long lies along the positive y-axis and grips a bolt at the origin, and that you apply a force in the direction of the vector (0, -4,3) at the end of the wrench. Find the magnitude of the force needed to supply 100 Nm of torque to the bolt.
