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 . Any help would be greatly appreciated.

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

 

You need to post a free body diagram...

 

hi
there is no pdf try again

 

Hi Mechaboy,

Thanks for having a look. I cant seem to upload PDFs or maybe just cant see where.

I have attached a link to a dropbox where the problem is. Maybe this will work.

Help much appreciated.

 

hi
i have downloaded pdf . do you wanna find the force on that green square?

 

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.
