Worked Example
Verified calculation
Given:
- High-side rope tension = 24500
- Low-side rope tension = 11800
- Brake drum or sheave radius = 0.25
Expected Result:
- Brake torque = 3175
Engineering Interpretation:
Under the given input conditions, the calculated result is: Brake torque = 3175 N·m.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.
Formula / Method
brake torque = (high-side rope tension - low-side rope tension) * brake drum or sheave radiusBrake torque.
