Week 011 Rotational Equilibrium And Rotational Dynamics Pdf This chapter discusses rotational equilibrium and rotational dynamics. it covers topics like torque, equilibrium conditions, center of gravity, rotational kinematics, rotational dynamics, rotational energy, and angular momentum. The document discusses rotational equilibrium and rotational dynamics. it defines torque as a tendency to cause rotation and describes how torque depends on the position and magnitude of an applied force. torque is calculated as the cross product of the position vector and force vector.

Static equilibrium occurs when an object is at rest – neither rotating nor translating. total torque is zero respect to any rotational axis. if the net torque is zero, it doesn’t matter which axis we consider rotation to be around; we are free to choose the one that makes our calculations easiest. What are some examples of static rotational equilibrium? problem solving hint: use the convention counter clockwise (ccw) is positive and clockwise (cw) is negative. Determine the upward force exerted by the biceps on the forearm (f) and the downward force exerted on the joint ( r). a uniform horizontal beam, 5.00 m long, weighing 3.00 x 102 n, is attached to a wall by a pin connection, that allows the beam to rotate. its far end is supported by a cable as shown in the figure. M25a: rotational equilibrium and rotational dynamics introduction: by newton’s first law of motion, a body is in translational equilibrium when the net force.
