Calculating Forces on a Domestic Wind Turbine During Extension/Retraction
 
1. The problem statement, all variables and given/known data
Hi
I need help in calculating the forces on a domestic wind turbine that is retracted/extended by a hydraulic ram. It is very simular to the following photo:

I need to calculate the forces at the hinge and where the ram attaches. I have all the relevent dimensions and masses:

The turbine is 200kg and is on top of a 15m shaft. The shaft is 3000kg and is uniform so the center of gravity is 7.5m up in the centre. The hinge is 1m of the ground and the ram attaches 2m above the ground.

Diagram better explains it : http://farm8.staticflickr.com/7065/6...e0b353ef_z.jpg

I would be very appreciative of any help.

Thanks,
Shane
