Torque Torque ● The tendency of a force to rotate a body about some axis ● The same force will be a lot more effective at rotating an object such as a nut with a wrench, or a door opened at the handle instead of a hinge. ● The units of torque are: ○ [τ] = [r][F] = Nm Reformatting Newton’s Second Law ● τ = Iα More Torque ● τnet τ1+ τ2+ ... ● Counterclockwise is positive Examples ● A meter stick (1kg) has a pivot in the center and a two 2 kg masses are located at x = 0.3m to the right of the pivot and y = 0.4m to the left of the pivot. Find the net torque. ● ● A 2-m-long board weighing 50 N extends out over the edge of a table, with 40% of the board’s length off the table. How far beyo
