We are using the motors to pull down our catapult which is connected to surgical tubing at the other end of a fulcrum. The calculated value for the tubing pull force is 516 lbs when the tubing is completely stretched (I realize that is a ton of force). The mechanical advantage that our winch has is 4 due to the length of our catapult arms (the winch will be connected to the end of the catapult arms).
It's a lot of info to explain let me know if I missed anything
