Hi guys, was doing some thinking on torque, we all know that we can calculate torque by using T= Force x radius. But let's say if i have a cylinder of mass x kg which has a radius of r, sitting vertically on the floor (flat surface on the floor). How do i determine how much torque is required to start rotating this cylinder?
I am thinking that it will probably be similar to pushing / pulling a box on a surface, the box will only start moving once the static friction is exceeded, it is similar in this case that cylinder only rotates once static friction is exceeded, which means F=mu x N should come into this, i am thinking maybe Torque required to turn = mu x N x radius??
Thanks all~
