Gravitation:
Gravitational potential and intensity, calculation
of gravitational potential and intensity due to thin spherical shell, thick
spherical shell, sphere, circular disc etc. Compound pendulum, measurement of
‘g’ by bar and Kater’s pendulum.
Elasticity:
Hooke's law, work done in strain,
elongation strain, volume strain, shearing strain, Young's modulus, Bulk
modulus and rigidity modulus and their inter-relationship, Poisson’s ratio, torsion
in a cylinder, twisting couple, variation of strain along its length. Bending
of beams and cantilevers in different cases: loaded at free end, loaded
uniformly, bending moments.
Viscosity:
Equation of continuity, Energy of a
liquid in flow, Bernoulli's theorem, critical velocity, Reynold's number,
Poiseuille's equation, motion in a viscous medium: Stoke's law, streamline and
turbulent flow.
Surface tension:
Surface tension as a molecular phenomenon, surface tension and surface energy. Excess pressure on curved liquid surface ( spherical bubble and drop). Theory and experimental determination of surface tension of liquid by ripple method.
