A steel cable with a radius of \[\text{a  }\!\!\upsilon\!\!\text{  = a}\] cm supports a chairlift at a ski area. If the maximum stress is not exceed\[\text{P +  }\!\!\rho\!\!\text{  gh + }\frac{\text{1}}{\text{2}}\text{  }\!\!\rho\!\!\text{ }{{\text{ }\!\!\upsilon\!\!\text{ }}^{\text{2}}}\text{ = a}\] what is the maximum load the cable can support?

Answer:

Maximum load = maximum stress x area of cross-section                 \[\upsilon \]
