Place one weight on a balance and follow both pan heights

Original, untested video brief. No input image or generated result is supplied.

1. Task and boundary

Place one small weight on the left pan of a simple balance. Follow the left pan descending and right pan rising as the beam tilts around its fixed center. End when the beam reaches its existing modest travel stop, with the operating hand clear.

This original plan is untested. Use a two-pan balance with a visible center pivot and an existing mechanical stop. Exclude digital scales, sliding counterweights, pulley systems and numerical weighing claims. The shot reviews motion after one visible load is transferred.

2. Authorized first frame

Use your own or authorized photograph or accurate drawing. Both empty pans start at similar heights, hanging from opposite ends of a level beam. The center support and small travel stop are clearly visible. One original hand holds a small plain weight just above the left pan.

Choose a frontal view that separates both pans, suspension points and the beam. Leave vertical clearance for their opposed movement. Keep the base against a fixed background reference and avoid printed scales that imply calibrated readings.

3. Use the generator

Open the current image-to-video generator in a mode accepting your authorized first frame. Paste the prompt; check settings and cost before submission. Nothing runs automatically.

4. Prompt and timing

Start from my authorized image of a two-pan balance with a level beam, fixed center pivot, visible travel stop and one hand holding a small weight above the left pan. Lock the camera, lighting and base. Lower the original weight into the left pan and release it. As its load transfers to the pan, let the left beam end and pan descend while the right end and pan rise around the same center pivot. Keep both pans hanging beneath their original beam attachments rather than rotating rigidly with the beam. Preserve the weight in the left pan after the hand withdraws. Stop the beam at the existing modest mechanical limit and let the suspended pans settle briefly. No additional weight, moving center support, teleporting pan, numerical reading, camera motion, cut or return to level.

1. Establish, first fifth: locate the pivot, stop, empty pans and weight before contact.
2. Load, middle three fifths: follow placement, hand release and opposing height changes after load transfer.
3. Settle, final fifth: inspect contact with the existing travel stop and both pans with the hand clear.

5. Inspect the output

For each check, record a frame or time, observation and pass, fail or inconclusive judgment.

• The weight visibly reaches the left pan before the main tilt develops.
• The same center pivot remains fixed while the beam changes angle.
• Left and right pan heights change in opposite directions, retaining their original attachments.
• The weight stays inside the left pan after release without sinking through it.
• The beam stops at the existing limit rather than freezing freely at an arbitrary angle.
• If the hand continues supporting the weight, record load transfer as inconclusive.

6. Fix one failure

• Both pans descend: keep the beam rigid and explicitly pair left descent with right ascent.
• The base tips: anchor the base and center support before assigning beam rotation.
• Pans rotate with the beam: preserve hanging attachments and show each pan beneath its endpoint.
• The tilt begins too early: place the contact and release beats before the main response.
• The ending floats: include the original physical stop in the input and keep its contact visible.

7. Ending and limits

Finish with the weight in the lower left pan, the right pan raised and the beam resting at its existing stop.

Save your result, authorized input, exact prompt, settings and inspection notes.

No H3 execution, mass reading, torque calculation or balance calibration is supplied. Unequal displayed heights cannot establish an exact weight difference.

The pulley task couples vertical travel through a rope. Here a newly placed load causes a rigid beam to pivot, with both pans hanging from its ends. A different weight shape remains the same task.
