Unformatted text preview: 1 Physics 1D03 - Lecture 10 Torque Torque Text Sections : 10.6, 11.1 Torque in 2 and 3 dimensions Practice problems: Chapter 10, problem 35 Chapter 11, problems 1, 5, 9 Physics 1D03 - Lecture 10 An unbalanced force applied to an object causes it to move (accelerate). F a Even with no net force, the object is not necessarily in equilibrium. A net torque will cause it to rotate. F-F Torque is what causes rotation 2 Physics 1D03 - Lecture 10 Quiz A weight W is placed at one end of a light plank. What weight should be placed at the other end so that the plank will balance on a pivot placed 1/3 of the way along the plank? a) 3W b) 2W c) W d) W e) 1/3 W L/3 2L/3 W ? Physics 1D03 - Lecture 10 R F Each force produces a torque, (tau), which tends to rotate the plank about the pivot. Torque is proportional to the force and to the distance from the pivot: torque = (force) x (length of lever) (when the force is perpendicular to the lever) 3 Physics 1D03 - Lecture 10 A force directed toward the axis of rotation produces no torque.A force directed toward the axis of rotation produces no torque....
