Hello,


I am designing a fixture which is having a component clamped by a hydraulic cylinder operated at 80 bar ( lets say bore 50 mm) . when the cylinder is clamping the component, the force applied by the cylinder while clamping doesnot make any difference to the overall weight of the fixture.


my doubt is how the force is getting neutrailised ? why the clamping force not increasing dead weight of fixture

 

Newtons Third law. For every force there is an equal and OPPOSITE reaction.

The clamp load and the reaction force of the cylinder body are INTERNAL to your fixture. The weight does not change.

Draw a free body diagram of your tool and place all the forces and you will have your answer
