Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to calculate the force required to move the wheel on a standard wheelchair from stand still and then consistently over a flat surface?

I understand that this has to with the amount of weight that is trying to be moved, this being the weight of the user (approx. 68kg) and the wheelchair (approx. 16kg).

I also understand that the equation for torque requires the distance from the force applied to the axis of rotation which is approximately 0.33m.

Also I have found the average pushing force for a seated human to be roughly 130N.

I feel as though I have enough information to find out the answer I need however I'm unsure exactly how to apply it or if I'm miles off with how I think I need to calculate it.

Any help would be appreciated!
