The modulus of elasticity is dimensionally equivalent to
strain
force
stress
coefficient of viscosity
A wire of length L and area of cross-section A is stretched through a distance x metre by applying a force F along length, then the work done in this process is : (Y is Young's modulus of the material)
A uniform plank of Young's modulus Y is moved over a smooth horizontal surface by a constant horizontal force F. The area of cross-section of the plank is A. The compressive strain on the plank in the direction of the force is
The following four wires of length L and radius r are made of the same material. Which of these will have the largest extension,when the same tension is applied ?
L = 1000 cm, r = 0.2 mm
L = 2000 cm, r = 0.4 mm
L = 3000 cm, r = 0.6 mm
L = 4000 cm, r = 0.8 mm
The ratio of hydraulic stress to the corresponding strain is known as
Young's modulus
compressibility
Rigidity modulus
Bulk's modulus
D.
Bulk's modulus
The ratio of hydraulic stress to the corresponding strain is known as bulk modulus.
i.e,
A spring is stretched by applying a load to its free end. The strain produced in the spring is
volumetric
shear
longitudinal and shear
