Torque Exercises - Solutions. We have three methods for calculating torque about a particular point. R θ Force acts here. F Force acts here. R Force acts here. Use this method if both R and θ are easy to find. Use this method if the lever arm is easy to find. Use if Rr and Fr are easy to break into components.
A force of 6.0 N is applied perpendicular to the rod at a distance of 1.2 m from the pivot causing a ccw torque, and a force of 5.2 N is applied at the end of the rod 3.0 m from the pivot.
What is torque? Crudely speaking, torque is "twisting or turning ability" of a force that can: change the angular velocity of an object (i.e. speed up or slow down rotation) cause a twisting or bending distortion of an object. A force with a "line of action" that does not cross the axis of rotation results in torque. Note:
F=ma for rotation: t=Ia. Use F=ma, t=Ia to solve for a, a, tension, time. Use conservation of energy to solve for speed. Can choose any axis or pivot around which to compute torques. Trick of the trade: If there is a force on the pivot, the torque it produces is 0!
Determine the force and distance from the axis of rotation that would result in a net moment (torque) of zero. The total negative (clockwise torque) is 375 N.m.
