The tension in a pulley belt is 300 N when stationary. The smaller pulley has a diameter of 300 mm and a speed of 1420 rev/min. The coefficient of friction between the belt and the pulley is 0·4 and the angle of lap is 160°. (1) Calculate the tension in each side of the belt at operating speed.  (2) Determine the power transmitted when the belt is on the point of slipping.  If the pulley system uses a flat belt of CSA 500 mm² and density 1300 kg/m3, determine: (3) The power transmitted, when the mass of the belt is taken into consideration.

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.
