Step Climbing Energy = Weight x Step Height

Constant Step Climbing Work = Force1 x Radius x Arc b
 
Weight x Step Height = Force1 x Radius x Arc b

Step Height = 18 cm ; Step Lenght = 28 cm; Radius = 25 cm

Force1 = (Weight x 18 cm) / (30.7 cm x 1.203 rad) = 0.59 x Weight

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

Force1 = 0.69 x Force2
