I'm looking for some advice for my final year project at university. My project is a design of an exercise machine for wheel chair users . The machine will look like a standard wheel chair but the wheels are a couple of centre meters off the floor. I want to add a mechanism to the wheels which would add resistance for when the user is pushing the hand rim . I was thinking about having a pulley but I can't find anything about resistance pulleys. Any advice?
