Final answer:
To change the revolutions per minute of equipment, you can change the size of the pulley.
Step-by-step explanation:
The revolutions per minute (RPM) of equipment can be changed by changing the size of the pulley. A pulley is a simple machine that consists of a wheel with a grooved rim and a rope or cable that runs along the groove. By using different-sized pulleys, the speed at which the equipment rotates can be altered. For example, if a larger pulley is used, the revolutions per minute will decrease, whereas a smaller pulley will result in higher RPM.
