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
A spring is stretched by applying a load to its free end. The strain produced in the spring is
volumetric
shear
longitudinal and shear
