Question

a pulley revolves at a speed that is inversely proportional to its diameter. a pulley with the diameter of 12 cm is belted to a pulley of diameter 8 cm l. if the smaller pulley is revolving at a rate of 96 rpm ( revolution per minute ),how fast is the larger pulley revolving

Answer 1

Answer:

RPM for larger pulley is 64 rpm.

Step-by-step explanation:

Pulley 1 - Diameter - 12, Rate - x

Pulley 2 - Diameter - 8, Rate - 96 rpm

So, 12 * x = 8 * 96

∴ x = 8 * 96 / 12

∴ x = 768 /12

∴ x = 64

Hence, rpm for larger pulley is 64 rpm.

Answer 2

Answer:

THE PULLEY IS RESOLVING AT A SPEED OF 64 rpm
