Chairliftop
Hello!
First off, here is a video of what a roll back is:
Here's my question:
How could I determine how much of a load the lift is carrying for there to be a loss of friction between the haul rope (the cable) and the bull wheel (the main wheel at both the top and bottom terminals), causing the lift to run backwards?
Here's my attempt:
I know I am going to have to find the friction coefficient between the rubber lining of the bull wheel and the haul rope.
The chairlift I am talking about has the following:
- 169 Chairs (82 are loaded at one time)
- Each chair has a 6 person capacity
- Assuming the average person weights 137 pounds
Besides that, I need help figuring out when a roll back would occur due to a loss of friction between the rope and the bull Wheel! Help!
Note: I have never taken physics before, so an explanation in basic terms would be great!
Thanks!
