Following is a question for mechanical engineering students. Please, provide
a concise answer and a brief explanation. I will compile and post the answers
to the list.
MHD is a sensor designed to measure angular velocities of rigid bodies. Suppo
se an MHD is attached to a moving (translating and rotating) rigid body, so th
at it measures angular velocities wrt the body-fixed local coordinate system.
If the MHD measures angular velocities in a body-fixed local coordinate syste
m, then these angular velocities should always be equal to zero since the body
does not rotate wrt to the body-fixed coordinate system. The question is: wh
at does MHD measure? Why?
