An industrial overhead door has a chain and sprocket system designed to reduce the force needed by an operator to open and close

the door. The system consists of two individual systems that are connected through a live axle shaft. To operate the door, the operator pulls a continuous loop of chain over a fixed 22 tooth sprocket that is attached to a live axle shaft. The second 22 tooth sprocket is attached to a drum that drives the door. What is the overall system ratio?

evablogger [386]
The weight of the boulder is 3800 N, therefore its mass i s
3800/9.8 = 387.755 kg

If the horizontal acceleration is 12.8 m/s², then the horizontal force applied is
F = (387.755 kg)*(12.8 m/s²) = 4.963 x 10³ n = 4.963 kN
