A 90 cm pulley transmits 75 kW at 750 rpm. The arc of contact between the belt and pulley is 135 degrees, the coefficient of friction between belt and pulley is 0.25 and the safe working stress of the belt is 2200 kPa. It is required to find the tangential force at the rim of the pulley in Newton; the effective belt pull in Newton and the width of the belt used if its thickness is 5mm.

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.
