Elastic Behaviours, Stress, Strain, Hookes’ Law, Stress-Strain diagram, Young’s modulus, Bulk modulus, Shear modulus of rigidity, Poisson’s ratio, elastic energy.
Mechanical properties of fluids:
Pressure due to a fluid column, Pascal’s law and its applications (hydraulic lift and hydraulic brakes) effect of gravity on fluid pressure. Surface energy and surface tension, angle of contact, excess pressure across a curved surface, application of surface tension ideas to drops, bubbles and capillary rise. Viscosity, Stoke’s law, terminal velocity, streamline and turbulent flow, critical velocity, Bernoulli’s theorem and its application.
