Who invented the compound pulley?
The compound pulley system was invented by Archimedes, an ancient Greek mathematician, around the 3rd century BC. Archimedes is also known for his contributions to geometry, physics, and engineering.
What were pulleys made out of when they were first invented?
Pulleys were first made out of wood, stone, or metal when they were first invented. These materials were used to create the wheel and the axle necessary for the pulley mechanism to function.
What is the velocity ration of a pulley?
The velocity ratio of a pulley system is the ratio of the rotational speed of the driving pulley to the driven pulley. It indicates how the speed of the driven pulley relates to the speed of the driving pulley. The formula is: Velocity Ratio = Diameter of driving pulley / Diameter of driven pulley.
How do you calculate velocity ratio in a pulley?
To calculate the velocity ratio in a pulley system, divide the diameter of the driving pulley by the diameter of the driven pulley. This ratio indicates how much faster or slower the driven pulley rotates compared to the driving pulley. It helps to determine the speed or force transmission in the pulley system.
