Static Equilibrium and Elasticity Chapter 12
... Regardless of the number of forces that are acting, if an object is in translational equilibrium and if the net torque is zero about one axis, then the net torque must also be zero about any other axis. The axis can pass through a point that is inside or outside the boundaries of the object. Conside ...

... The equation F=ma is equivalent to the equation T=I α. When a body of mass m (kg) is subjected to a Force F (N) it is accelerated by acceleration a (m/s2). Similarly, when a body that can rotate around an axis and has a moment of inertia of I (kg m2) is subjected to a torque T (N m), its rotational ...
