Question: B 1 : The power output from an engine is measured by means of a belt brake arrangement as shown in Figure B 1 .

B1: The power output from an engine is measured by means of a belt brake arrangement as shown in Figure B1. The brake-drum diameter is 800 mm , over which a belt supports two masses of 50 kg each. One side of the belt is attached to a spring balance which reads 375 N . the engine speed is 450 rpm. Calculate the power dissipated in friction between the belt and the drum.
