The compound shaft shown is built-in at the two ends. It is subjected to a twisting moment $$T$$ at the middle. What is the ratio of the reaction torques $${{T_1}}$$ and $${{T_2}}$$ at the ends?

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

During the phase change of a pure substance:

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