Need help determine force from cylinder linkage

Click For Summary
To determine the downward force of a rod from a cylinder pressure and mechanical linkage, it's essential to analyze the system using linkages, vectors, and moments. Calculating moments about the pivot is a valid approach, but accurate results depend on detailed information about the linkage's centers of mass, lengths between pins, and coordinates of fixed points. The force transfer function will change based on the mechanism's attitude. The goal is to express the bucket downforce as a function of hydraulic pressure. Accurate calculations require precise measurements and a clear understanding of the mechanical setup.

How can I determine the downward force of the rod with the given cylinder pressure and mechanical linkage? Do I sum my moments about the pivot? I calculated M=950xCOS(75.732)x7.81 + (X)SIN(63.414)x9.4 which resulted in 1828lbs. I get 217 lbs which does not seem right.

Welcome to PF.

What a confusing picture.
If that is an auto-leveling front-end-loader mechanism, I would solve it using linkages with vectors and moments. To do that, I would need details of the linkage centers-of-mass, lengths between pins, and the coordinates of all fixed point pins on the loader frame.
The force transfer function will vary depending on the attitude of the mechanism.
The aim would be to find the bucket downforce as a function of hydraulic pressure.
 

Thread 'Measuring Deer Antler Volume'

My idea is that I want to use immerse Whitetail Antlers in a fishtank to measure their volumetric displacement (the Boone and Crockett system is the current record measurement standard to place in a juxtaposition with) I would use some sight glass plumbed into the side of the tank to get the change in height so that I can multiply by the tank cross-section. Simple Idea. But... Is there a simple mechanical way to amplify the height in the sight glass to increase measurement precision...
