Question 2
The state of plane stress in a plate of 100 mm thickness is given as σxx = 100 N/mm2, σyy = 200 N/mm2, Young’s modulus = 300 N/mm2 and poisson’s ratio = 0.3. The strain developed in the direction of thickness i.e. in z–z direction, is ______ mm/mm.
Question 3
The Poisson ratio of a material is zero. The ratio of bulk modulus to modulus of rigidity is
Question 4
Statement 1: The change in volume of rubber due to direct stresses would always be zero.
Statement 2: Poisson’s ratio for ideal rubber is zero.
Question 5
A material under the action of tensile load experience the longitudinal strain equals to 0.0045. The lateral strain in the material if Poisson ratio of the material is 0.30.
Question 6
A cylindrical piece of steel, with a diameter of 60mm and length 100 mm, is subjected to an axial compressive force of 40,000 kg. If bulk modulus is 1.7 x 106 kg/cm2 and poisson’s ratio is 0.25 than the change in volume of the cylindrical piece is
Question 7
A mild steel bar, 1.5 m long, has a square section 40 mm × 40 mm. The bar is subjected to a two-dimensional stress,
