The trap door OA is raised by the cable AB, which passes over the small fric- tionless guide pulleys at B. The tension everywhere in the cable is T, and this ten- sion applied at A causes a moment Mo about the hinge at O. Plot the quantity Mo/T as a function of the door elevation angle 0 over the range 0 s 0 90° and note min- imum and maximum values. What is the physical significance of this ratio?
