why we are not using the unit joule for torque instead of N-m.
Answer Posted / pramit kumar
joule is also N-m, but joule is associated with heat but
for the unit of torque we must use N-m. Moreover heat
(joule) is a low grade energy and work (torque or shaft
work) is a high grade energy, low grade energy can be
completly fully converted to high grade but the vice versa
is not true. If numericaly we need to convert work to heat
then we must divide work by joule constant.
