Verified calculation
Given:
- Load mass = 4
- Horizontal distance from lumbar spine to load center = 0.25
- Vertical lift height (from floor) = 0.75
Expected Result:
- Manual handling load index = 366.53386454183
Engineering Interpretation:
Under the given input conditions, the calculated result is: Manual handling load index = 366.53386454183 dimensionless.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
Formula / Method
manual handling load index = 23.0 * (load mass / (horizontal distance from lumbar spine to load center + 0.001)) * pow((1.0 - abs(from floor - 0.75) / 0.5), 0.5)Formula family: formula_ergonomics_computer_workstation_manual_handling_load_calculator
