Calculate the total torque (magnitude and direction) for each of the following cases shown below. You can assume the "bar" the masses are attached to is massless. The top point of the triangle represents the pivot point for the system. Be sure to include the magnitude and the direction.
Homework Answers
a)
torque = 10*10^-3*9.8 *0.20 =0.0196 N.m CW
b)
torque = 10*10^-3 *0.20 =0.0196 N.m ACW
c)
10*10^-3 *0.20 - 10*10^-3 *0.20 = 0 N.m no direction
d)
10*10^-3*9.8 *0.20 - 10*10^-3*9.8 *1.1 = 0.0882 N.m ACW

Torque and Angular Acceleration Learning Goal: To understand and apply the formula τ= Iα to rigid objects rotating about a fixed axis. To find the acceleration a of a particle of mass m, we use Newton's second law. Fnet =ma, where Fnet is the net force acting on the particle. To find the angular acceleration a of a rigid object rotating about a fixed axis, we can use a similar formula: Tnet = Ia, where Tnet=∑T is the net torque acting on the object...
