PPT-Torque & Equilibrium

AP Physics Torque             Turning or twisting effects due to a force The product of force and perpendicular distance from pivot point aka level arm Can produce . - Class. . 20. Today:. Gravitational Torque. Rotational Kinetic Energy. Rolling without Slipping. Equilibrium with Rotation. Rotation Vectors. Angular Momentum. Pre-class reading quiz on Chapter 12. 11.1 - Torque. Increased Force = Increased Torque. Increased Radius = Increased Torque. 11.1 - . Torque. Only the tangential component of force causes a torque:. 11-1 Torque. This leads to a more general definition of torque:. o. This has . NOTHING. to do with torque but it comes up when you . google. images…go figure.. A body in translational equilibrium will have no acceleration in the x or y directions. However it still could be . AP Physics C. Torque. So far we have analyzed translational motion in terms of its angular quantities. But we have really only focused on the kinematics and energy. We have yet to add dynamics (Newton's Laws) to the equation... Rotation, Torques and The Conditions for Equilibrium. Conditions for Equilibrium. Q: . How do you know when a body is in equilibrium? What two. . distinct kinds of motion can a body have when it is not in “balance”?. Human Movement. Basic Biomechanics, 4. th. edition. Susan J. Hall. Objectives. Define torque, quantify resultant torques, and identify the factors that affect resultant joint torques. Identify the mechanical advantages associated with the different classes of levers and explain the concept of leverage within the human body. What determines whether an object will rotate when a force acts on it? . Why doesn’t the Leaning Tower of Pisa rotate and topple over? .
