Hi
I am currently studying design engineering and my lecturer has left just before an exam. I really don't know how to find the magnitude and direction of the total force transmitted to the connecting rod at A. Any help would be greatly appreciated!

A drawing or sketch of point A would help. And are the loads to include those due to accelerations of the compressor parts? What other load components are there (gas compression, I'm imagining)?
