This study shows when wheelchairs and baby carriages begin to move at a gentle slope in a certain angle of inclination. We used a swing road to experiment with wheelchairs and baby carriages for an angle of inclination to see when they begin to move.
Results of Experiment:
1. Wheelchairs and baby carriages will not move if the frame sat down cross position from incline.
2. If the frame is moved in the direction of the incline, the angle of 1-2 degrees begins the wheelchair to move downward and 2-3 degrees for baby carriage.
