DESIGN A WORM GEAR THAT CAN LIFT A VERTICAL LOAD OF 5000 LBS IN A DISTANCE OF 30 FT IN 1 MINUTE. Use the pitch of the worm as 0.75 inches and pitch diameter of 3 inches. Assume the pressure angle is 14 ½ 0 and the coefficient of friction is 0.12 and the wheel has 40 teeth and a pitch diameter of 10 inches.   (Note:   The diameter of the drum that lift the load has the same diameter of the worm wheel).

Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.
