All the Best! 1 / 10 Bulk modulus is defined as ΔV/V ÷ stress Stress ÷ ΔV/V Strain ÷ stress Stress × strain 2 / 10 When a wire is stretched, its volume Increases slightly Decreases slightly Remains constant Becomes zero 3 / 10 Unit of shear modulus is N Pa N m Dimensionless 4 / 10 A cube under uniform pressure experiences change in Volume Shape Length Area 5 / 10 Which factor does NOT affect Young’s modulus? Nature of material Temperature Impurities Shape of body 6 / 10 For a material under elastic limit, doubling stress results in strain Remaining same Becoming half Becoming zero Doubling 7 / 10 Maximum value of Poisson’s ratio in stable, elastic materials is 0.25 0.33 0.5 1 8 / 10 Elastic limit is always Greater than proportional limit Less than proportional limit Equal to proportional limit Zero 9 / 10 A wire of radius r is replaced by wire of radius 2r. Extension of the wire after applying same force becomes Same Half One-fourth Double 10 / 10 A wire is stretched beyond elastic limit. On removing force, wire Regains original length Becomes shorter Becomes longer Breaks Your score is 0% Restart quiz
