Let u and v be vectors and consider the parallelogram that the two vectors make. Note: For i x j the magnitude is 1 and the direction is k, hence i x j = k. A 20 inch wrench is at an angle of 30 degrees with the ground. A force of 40 pounds that makes and angle of 45 degrees with the wrench turns the wrench. Find the torque.
