A circular rod of diameter $$d$$ and length $$3d$$ is subjected to a compressive force $$F$$ acting at the top point as shown below. Calculate the stress at the bottom-most support point A.

The number of degrees of freedom of a five link plane mechanism with five revolute pairs as shown in the figure is:

When a system executes an irreversible cycle:

The relationship $$\,{\left( {\partial T/{\partial _p}} \right)_h} = 0$$ holds good for :
