Design a variable resistance rowing exercise machine that has a direct digital readout of the instantaneous energy expenditure rate of the user. This means you have to specify or design transducers that measure the instantaneous work rate (i.e., power) done on the machine. This power can be absorbed by the machine either electrically or mechanically.
Provide assembly and detail drawings of your design plus specify all the electronics necessary to process the transducer signals and provide the proper digital output.
