      Hi Guy,

      I am only new to this forum so i hope this post goes ok.

      I am trying to find out what force is required to rotate the bin about a pivot point using a hydraulic cylinder[​IMG] . Any help would be greatly appreciated.

      I have tried to link a pdf of the problem. Hope it works. Thanks in advance.

      Hi,

      The 2 dimensions represent the closed centre dimensions and open centre dimensions of a hydraulic cylinder. The green box represents a bin which will be filled with a mass no greater than 400kg. I am trying to calculate the force required from a hydraulic cylinder to rotate the bin around the pivot point when fully loaded.

      Thanks.

      Hi Craygon,

      I tried to solve it using vectors with a force acting downward and a force acting inward with the force I require being the resultant vector.

      I don't think this method holds through when thinking of it in 3D. Am I way off the mark with this.

      Thanks.
