SYSTEMS OF PULLEYS
What is Systems of Pulleys? Differentiate first, second and third Systems of Pulleys.
The following three systems of pulleys are commonly used :
1. First system of pulleys.- For such a system, velocity ratio is:
where
n = Number of pulleys
2. Second system of pulleys. – For this system, velocity ratio:
3. Third system of pulleys.- For such a system, velocity ratio:
