Quick answer: Only if the required balancing torque is sufficiently constant or the mechanism compensates for its variation. A changing gravity moment requires a separate load analysis.
Can constant torque balance a hinged load through every angle?
A hinged load's moment arm changes with angle. Selecting a spring from one favorable position may cause drift elsewhere. Use the actual center-of-mass location and orientation to calculate or measure the load curve before considering a constant-torque solution.
A practical verification method
Overlay measured load torque and spring output through the full angular range; identify positions needing holding friction or another mechanism.
| Item | What to record | Purpose |
|---|---|---|
| Reference configuration | Part or assembly identity and drawing revision | Make comparisons traceable |
| Test conditions | Relevant position, direction and operating condition | Compare the same characteristic |
| Decision evidence | Overlay measured load torque and spring output through the full angular range; identify positions needing holding friction or another mechanism. | Resolve the specific question before approval |
Use the result in an engineering request
Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
