ACTIVITY 1: Let's Investigate Torque Directions: Read the statements/questions carefully. Choose the letter of the correct answer. 1. Torque is a and its direction can be determined using A. scalar; right-hand rule C. vector; right-hand rule B. scalar; left-hand rule D. vector; left-hand rule 2. The magnitude of the cross product of vectors A and B is C. AxB |A||B| cos 0 A. AxB 1A||B| sin O %3D %3D B. AxB AB sin 0 D. AxB AB cos 0 For items 3-5, consider figure 3. One end of fixed, end tree end the stick is attached to a plank of wood. 3. The stick rotates when a force is Figure 3 applied on its end and is directed along the A. fixed; z axis C. free; x axis B. free; z axis D. free; y axis 4. When torque is zero, the stick will not rotate. Which conditions result to a zero torque? 1. The force is applied on the fixed end of the stick. II. The force is applied along z axis at the middle of the stick 11I. The force is applied along z axis on the free end of the stick. IV. The force is applied along x axis on the free end of the stick. A. I only C. Ill and IV B. I and II D. I and IV 5. The stick is pushed near its free end along-z axis. What is the direction of the torque? A. along +x axis C. along +y axis B. along -x axis D. along -y axis ACTIVITY 1: Let's Investigate Torque Directions: Read the statements/questions carefully.
