As long as the force is tangent to the swing of the lever; the force is a
vector whose magnitude can only be specified with its direction.  That is why
a beam torque wrench has a floating handle.  Having said that, if you are
hanging a dead weight from a lever in order to apply a known torque, use a
clevis between the weight and the lever, then stop when the lever is sorta
horizontal.
