- At what value of poisson’s ratio young modulus is equivalent to shear modulus?Figure 6.23 shows the tensile engineering stress– strain curve in the elastic region for a gray cast iron. Determine (a) the tangent modulus at 25 MPa (3625 psi) and (b) the secant modulus taken to 35 MPa (5000 psi).Evaluate bulk modulus, if modulus of rigidity and Poisson’s ratio for a material are 75 GPa and 0.3 respectively.
- The compressive strength of alumina quartz (Al2O3) is 2.1 GPa. A quartz tube is being used for a vacuum furnace. Both ends of the tube are constrained and cannot move. To what temperature can the tube be heated up from room temperature such that the tube won’t fracture due to the thermal stress?12.5 mm diameter steel rod is pinned between two rigid walls. The rod is initially unstressed. The rod's temperature is raised by 50 C. The coefficient of thermal expansion for steel is 11.7x10-6 1/ C and the modulus of elasticity is 210 GPa. What is the approximate axial force in the rod?Calculate the total strain energy in the post BD
- Please show a clear step-by-step solution. Thank you! What is the proportion of the alteration in length for Spring A to Spring B, supposing that both springs carry an equal amount of load? Springs A and B have the identical qualities, with the exception that Spring A has 12 times the number of turns as Spring B.And **The modulus of elasticity** (MPa) I need a clear step by step answer please :)What is the maximum value of KIc as per LEFM that can be determined from experiments on a 20 mm thick plate? yield strength= 500 MPa, E= 210 GPa, poission ratio=0.3.
