The sign of the torque is found using the right hand rule. The net torque can be found from summing the individual torques about a given axis.

(It is best to leave the units as N m rather than to express torque in joules.)

For an object rotating about a fixed axis, the angular momentum depends on how fast the object is spinning, and on the object's rotational inertia (also known as moment of inertia) with respect to that axis.
