Unfortunately, elevators can be out of order because of emergency or breakdown, and most of buildings have no 5-10% ramps like an alternative, because room is very expensive.



 Are you an ENTREPRENEUR

Are you CONCERNED about disabled accessibility?

 Do you think REDESIGNED STAIRS or WHEELCHAIRS could improve Universal Accessibility?

Step Climbing Energy = Weight . Step Height

Constant Step Climbing Work = Force1 . Radius . Arc b
 
Step Climbing Energy = Constant Step Climbing Work

Step Height = 18 cm ; Step Lenght = 28 cm; Radius = 30.7 cm

Force1 = (Weight x 18 cm) / (30.7 cm x 1.203 rad) = 0.4873 x Weight

Force2 = Weight . cos(pi/6) = 0.866 x Weight

Force1 / Force2 = 0.56 = Force Reduction Ratio
