Hello.
I am not an engineer but would really appreciate some help with a calculation for my PhD in biomedical sciences. I have a new exercise ergometer (see picture) and have been able to obtain the force applied (Newtons) to the load cells located underneath each foot pedal at 1hz. A motor moves the the 2 foot plates back and forth at 23rpm whilst the subject pushes against them. The velocity and distance remain constant so only the force applied (Newtons) varies.
I have completed one study with participants exercising on this new ergometer however for publishing purposes i need to convert my current integrated Newtons profile (n.min) into Watts.
I have measured the distance from the pivot point to the load cell as 54cm and the distance the foot plate moves back and forth as 16cm.
This is probably a really easy calculation but my medical head can't quite grasp it.
Any help would be greatly appreciated
