Mechanical Properties of Solids: NEET questions with solutions

NEET uses this chapter for Young's modulus and elongation numericals, comparisons between wires of different size, bulk modulus and compressibility, Poisson's ratio, elastic energy density and the features of the stress-strain curve. Marks are lost by leaving mm² or mm unconverted, using diameter as radius, and calling rubber more elastic than steel.
