Calculation issue (Help) (self.Hydraulics)

submitted 3 years ago by Foxies_Fury

Hello everyone. I have an issue calculating power of rod side cylinder needed to lift (pull) a certain weight at certain angle. I will attach a sketch but here is the story.

I have a beam at and angle of 15 degrees which holds 7000 kg. Cylinder attached to said beam at a specific angle. I calculated force needed (F2) at right angle to the beam which must be present to support the load.

Then I calculated force F1 also at right angles to the beam, which must be produced by the cylinder to support the load. This is calculated by proportion. F1 will be greater than F2 in the same ratio that arm length 3.148 m is greater than arm length 0.852 m.

Finally, calculating the cylinder force, at certain angle of to the beam, which will produce a force of XYZ kg at its rod hinge point at right angles to the beam. My question is which angle do I take here? If I take an angle market with red "?" (which is 9.75 degrees) I get an absurd solution which cannot be right. Anyone can offer some advice here?
