The number of revolutions of two pulleys is inversely proportional to their diameters. if a 24-inch diameter pulley making 400 revolutions per minute is belted to an 8-inch diameter pulley, find the number of revolutions per minute of the smaller pulley. a) 133 1/3b) 800c) 1,200
Answers: 1
= Diameter of bigger pulley = 24 inch
= Diameter of smaller pulley = 8 inch
= Speed of bigger pulley = 400 rpm
= Speed of smaller pulley
