Question

The diameter of pulley a is twice that of pulley d if pinion a rotates eight times clockwise

Answer 1

Given, the diameter of Pulley a is twice that of Pulley d. That means, a= 2d.

Now , if the pinion rotates clockwise 8 times for a, then it'll rotate 4 times for pinion d because it gets divided.

So the pinion rotates less for the Pulley d

Ans is 4 times.
