- A copper specimen subjected to the Brinell Hardness Test using hardened steel ball indenter of diameter 13 mm and the indentation diameter 3.78 mm is measured using an optical magnifying lens with a ruler. Draw the Brinell Hardness Test setup neatly and determine the force applied on the specimen. Take Brinell Hardness Number for copper as 1037. Surface Area of Indentation (in mm2) = Applied Force (in N) =A laminated [0/90/0/90]s graphite/epoxy beam is 1 mm thick, is 20 mm wide, and has 0.125 mm thick plies. The lamina properties are E1 = 180 GPa, E2 = 10 GPa, ν12 = 0.28, G12 = 7 GPa Xt = 1700 MPa, Xc = 1400 MPa, Yt = 40 MPa, Yc = 230 MPa (a) Determine the flexural modulus of the beam (b) How could the flexural modulus be improved without changing the ply materials, the number of plies, or the ply orientations? (c) Using the Maximum Stress Criterion for each ply, determine the magnitude of the maximum allowable bending moment that the beam can withstand. Which ply fails first?A square specimen of Magnesium Oxide is loaded in a 3-point bending test. If w = h = 6.2 mm is the dimension necessary for it not to fracture when a load of 494.0 N is applied and the flexural strength is 117.1 MPa, determine the separation between the load points.

- Estimate the tensile strength required to prevent cracking in a concrete-like material that is cast into a bar, 50 in. long, and is fully restrained at each end against axial movement. The concrete is initially cast and cured at a temperature of 100°F and subsequently cools to a temperature of 0°F. Assumethat the modulus of elasticity is 5 million psi and the thermal coefficient is 5 * 10-6 in./in./°F.(Solid Mechanics) A setup for single-edge-notch-bending (SENB) tests is shown below. Support rollers provide frictionless contact with the specimen, while a load is applied at the middle of the top surface of specimen. The thickness of the specimen is 10 mm and the height W 10mm. The properties for this ductile alloy are E = 70 GPa, v=0.3, σᵧ = 400 MPa, Kᵢ? = 25 MPa.m¹/². (1) Ignore any crack or defects in the material, what is the maximum static force that the specimen could carry before failure? (2) A cyclic load of low amplitude 2.8 kN is applied. Because of the cyclic load a defect is nucleated on the edge and grows into a fatigue crack of 2 mm length shown in the right. If the cycling is interrupted, what is the maximum static tensile force that the specimen could carry? (3) With more cycles, the fatigue crack keeps growing. Estimate the critical crack length (a range is fine) at which the plate will fail from the low-amplitude cyclic load 2.8 kN only. (maximum two iterations are…Determine if the flexural stress of the chocolate will increase or decrease if changes are made in thechocolate’s dimensions. Show solution. Answer Number 4 and 5
