For a simply supporting beam on two end supports the Bending Moment is maximum:

An elastic body is subjected to a tensile stress $$X$$ in a particular direction and a compressive stress $$Y$$ in its perpendicular direction. $$X$$ and $$Y$$ are unequal in magnitude. On the plane of maximum shear stress in the body there will be:

The layout of a steam power plant working on the Rankine Cycle with single stage regeneration is shown in figure. Assuming the exit stream from the re-generator to be saturated draw the corresponding ideal cycle on a Mollier Chart and derive an expression for the thermal efficiency of the cycle.
