Torque/Cross Product Worksheet
Torque/Cross Product Worksheet 1. What direction does the torque point? 2. F 5N , S 10m , and =60°. Find the magnitude of the torque (cross product) SF . 3. What is the cross product of C D if C 3iˆ 2 ˆj and D iˆ 4 ˆj ? Find the cross product of D C . a. Does the order matter? b. What is the angle between C and D? 4. Use the cross product to find the angle between A 2iˆ and B 3iˆ 3 ˆj . Does this angle make sense? Compare your answer to when you calculated the dot product in the chapter on work and energy.
