A steel compound cylinder is formed by shrinking a tube 400 mm outside diameter and 300 mm inside diameter on to one of 300 mm outside diameter and 200 mm inside diameter. When subjected to an operating pressure of 200 MPa, the radial pressure generated at the common interface is 75 MNm-².

Q4/ A. Explain why ceramic materials do not response to the plastic deformation processes? Also clarify why flexural test is applied to ceramics instead of tensile test? B. Estimate whether a cylindrical aluminum oxide sample will fail or not when it subject to flexural test to achieve flexural strength of 390 MPa knowing that the sample radius is 2.5 mm, separation distance is 30 mm, and the applied load is 620 N respectively.

In order to determine the bend strength of a specimen subjected to a three-point-bending test with a force applied at its mid-span, it is important to calculate first: The volume moment of inertia of the specimen. Or The polar moment of inertia of the specimen. Or The mass moment of inertia of the specimen. Or The area moment of inertia of the specimen

Annealed low-carbon steel has a flow curve with strength coefficient = 80,000 lb/in2 and strain-hardening exponent = 0.25. A tensile test specimen with gage length = 2.0 in is stretched to a length = 3.5 in. Determine the flow stress and average flow stress that the metal experienced during this deformation.  use correct stratgy  and correct E  0.55962

For a given homogeneous, isotropic, linearly elastic material, E = 15e6 psi and v = 0.3. Solve for the shear modulus. 2.1.1 Homogeneous, isotropic, linearly elastic materials For specimens undergoing small deformations, the stress-strain diagram often ex- hibits a linear behavior. Although this is a very crude approximation to the behavior of actual materials, it is a convenient assumption that is often used for preliminary evaluation. A linear relationship between stress and strain can be expressed as 01 = E €1, (2.1) where the coefficient of proportionality, E, is called Young's modulus or modulus of elasticity. Since strains are non-dimensional quantities, this coefficient has the same units as stress quantities, i.e., Pa. This linear relationship is known as Hooke's law. The elongation of a bar in the direction of the applied stress is accompanied by a lateral contraction that is also proportional to the applied stress. The resulting defor- mations for this uniaxial state of stress…

Q1/A structural part is 1-meter-long and subjected to a 50 KN load in which this part must be deformed elastically without experiencing any permanent deformation. If you know that part is made of steel, brass, aluminum, and Titanium alloys and the yield strengths and densities of these alloys are: 860 MPa, 7.9 g/cm³; 415 MPa, 8.5g/cm³; 310 MPa, 2.7 g/cm³; and 550 MPa, 4.5 g/cm³ respectively. Based on these criteria, rank the alloys from the heaviest to the lightest in weight.
