Mechanical Properties of Solids
This video explains bulk modulus and shear modulus of solids.
- assertion: young modulus for a perfectly plastic body is zero Reason:for a perfectly plastic body restoring. force is zero
- A horizontal rod is supported at both the end sand loaded at the middle. if L is length and Y is young modulus then depression is directly proportional to
- State Hook's law on what factors does the modulus of elasticity of a subtance depend?
- Is strain is dimensions less
- The area of cross section of a wire and its length are 1mm^2 and 2mm respectively.how much will be the work done to increase its length by 0.1mm . Youngs modulus of material of the wire=2.0*10^11n/m^2
- a wire 1 mm diameter and 1 m long fixed at one end is stretched by 0.01 mm when a load of 10 kg is attached to its free end . calculate young's modulus of elasticity.
- Define shear modulus and show that shear stress = shear modulus x theta (where theta is the angular displacement of cylindrical from the vertical position of the cylinder) .
- (a) Define Young's modulus of a material. (b) Define Bulk modulus of a body.
- (a) What do you mean by modulus of rigidity? (b) Which of the following state of matter has the least volume elasticity: solid, liquid or gas?
- What is the ratio of SI units to the CGS units of the modulus of rigidity?
