- TL;DR
- A hydraulic actuator force, F is 3000m from the right is lifting the platform upwards. The load 12000kg is UDL. How do I calculate for F?

Discussion Overview
The discussion revolves around determining the force required for an inclined platform supporting a load of 12,000 kg. Participants explore the implications of cylinder geometry, load calculations, and safety concerns related to the setup. The conversation includes technical reasoning and conceptual clarifications regarding the forces involved.
Discussion Character
- Technical explanation
- Debate/contested
- Conceptual clarification
Main Points Raised
- Some participants question whether the load is accelerating, suggesting that the force will depend on the cylinder geometry.
- Others assert that the cylinder geometry will be determined by the calculated force, indicating a dependency relationship.
- A participant calculates a moment based on the load and distance from the fulcrum, leading to a proposed load force of 185,100 newtons, while questioning if the mass of the tilting platform has been included.
- There is a request for clarification on whether the load is genuinely 12,000 kg or a mockup, raising concerns about the implications of a support failure.
- Some participants express skepticism about seeking advice on such a significant load in an informal forum context.
Areas of Agreement / Disagreement
Participants express uncertainty regarding the nature of the load (real vs. mockup) and its implications for safety. There is no consensus on the calculations or the appropriateness of discussing the scenario in the forum.
Contextual Notes
Participants highlight the need for clarity on the assumptions regarding the load and the potential risks involved, but these aspects remain unresolved.

Is it accelerating the load? ##F## will also be a function of the cylinder geometry.

No it's not accelerating the load. The cylinder geometry will be depending on the calculated force.

Moment: 12,000 kg at 3.000 m = 36,000 kg⋅m .
If one lift cylinder is located at 1.906 m from the fulcrum,
the load will be; 36,000 / 1.906 = 18,888. kg .
18,888 kg * 9.8 = 185,100 newton.
Have you included the mass of the tilting platform?

The load is 12,000 kg, and you are asking for advice on an Internet forum? Can you provide a link to your buisiness insurance company please?jr5 said:

I don't understand. Is the load really 12,000 kg, or is that mocked up too? If it's real, what happens if/when the support fails?jr5 said:
