<Rotation of a rigid body Torque about the z Axis Learning Goal: To understand two different techniques for computing the torque on an object due to an applied force. Imagine an object with a pivot point p at the origin of the coordinate system shown (Figure 1). The force vector F lies in the xy plane, and this force of magnitude Facts on the object at a point in the xy plane. The vector 7 is the position vector relative to the pivot point p to the point where F is applied. The torque on the object due to the force F is equal to the cross product 7 =7 x F. When, as in this problem, the force vector and lever arm both lie in the xy plane of the paper or computer screen, only the z component of torque is nonzero. When the torque vector is parallel to the z axis (7 = Tk), it is easiest to find the magnitude and sign of the torque, T, in terms of the angle between the position and force vectors using one of two simple methods: the Tangential Component of the Force method or the Moment Arm of the Force method. Note that in this problem, the positive z direction is perpendicular to the computer screen and points toward you (given by the right-hand rule ix j = k), so a positive torque would cause counterclockwise rotation about the z axis. Tangential component of the force ▶ ▶ Part A Part B Part C ▶ Part D Part E T = Submit Part F VE ΑΣΦ ▶ Part G 1 Find the torque T about the pivot point p due to force F. Your answer should correctly express both the magnitude and sign of T. Express your answer in terms of Ft and r or in terms of F, 0, and r.
