b) the Shear Modulus, G
Step by step
Solved in 4 steps
- A tensile test was performed on a metal specimen having a circular cross section with a diameter of 1 2 inch. The gage length (the length over which the elongation is measured) is 2 inches. For a load 13.5 kips, the elongation was 4.6610 3 inches. If the load is assumed to be within the linear elastic rang: of the material, determine the modulus of elasticity.A tensile test was performed on a metal specimen having a circular cross section with a diameter 0. 510 inch. For each increment of load applied, the strain was directly determined by means of a strain gage attached to the specimen. The results are, shown in Table: 1.5.1. a. Prepare a table of stress and strain. b. Plot these data to obtain a stress-strain curve. Do not connect the data points; draw a best-fit straight line through them. c. Determine the modulus of elasticity as the slope of the best-fit line.The data in Table 1.5.3 were obtained from a tensile test of a metal specimen with a rectangular cross section of 0.2011in.2 in area and a gage length (the length over which the elongation is measured) of 2.000 inches. The specimen was not loaded to failure. a. Generate a table of stress and strain values. b. Plot these values and draw a best-fit line to obtain a stress-strain curve. c. Determine the modulus of elasticity from the slope of the linear portion of the curve. d. Estimate the value of the proportional limit. e. Use the 0.2 offset method to determine the yield stress.
- A tensile test was performed on a metal specimen with a diameter of 1⁄2 inch and a gage length (the length over which the elongation is measured) of 4 inches. The data were plotted on a load-displacement graph, P vs. ∆L. A best-fit line was drawn through the points, and the slope of the straight-line portion was calculated to be P y∆L 5 1392 kips yin. What is the modulus of elasticity?A compact tension specimen is tested according to ASTM standard E399. The load displacement curve is shown in the Figure below with PQ= 120 kN (Type 1 curve). The specimen dimensions are B=0.5 cm, W=10 cm, and “a” =5 cm. If the materials yield stress is 600 MPa are the conditions correct for a valid K1C measurement? Please look up McEviley’s textbook on the thickness criterion for a valid fracture toughness value.In a simple tensile test using a cylindrical test specimen (Dia.=10mm), the applied force was 120 kN and the extension was 2%. Find the modulus of elasticity of that specimen. If the standard modulus of elasticity is 200 GPa, is this material accepted or not? and why?
- A tensile force of 20 kN is applied to a specimen with a gage length of 50mm. It isthen noted that the distance between the gage marks became 50.122mm. a,) What isthe modulus of elasticity of the specimen if its diameter is 10mm? b.) What is the axialstress of the specimen? Solution must have Free Body Diagram/drawing.A cylinder with a 6.0 in. diameter and 12.0 in. long is put under a compressive load of 150,000 lbs. The modulus of elasticity for this specimen is 8,000,000 psi. and Poisson’s ratio is 0.35. Calculate the final length and the final diameter of this specimen under this load assuming that the material remains within the linear elastic region.A cylinder with a 6.0 in. diameter and 12.0 in. length is put under a compressive load of 150 kips. The modulus of elasticity for this specimen is 8,000 ksi and Poisson’s ratio is 0.35. Calculate the final length and the final diameter of this specimen under this load assuming that the material remains within the linear elastic region.
- PROBLEM 3A tensile test is performed on a brass specimen 10mm in diameter using a gage length of 50mm. When the tensile load P reaches a value of 20kN, the distance between the gage marks has increased by 0.122 mm. What is the modulus of elasticity? Note: Please show complete solution with FBDA tension test is being conducted on a steel-rod specimen with a gauge length of L0=2 in and initial diameter of d0=0.5 in. Data were collected to form the conventional stress-strain diagram as shown. From the diagram, f = 74.0 ksi, e = 104.0 ksi , g = 85.0 ksi , and h = 0.15 in/in. Assuming that the strain remains constant throughout the region between the gauge points, determine the nominal strain ε experienced by the rod if it is elongated to L = 2.7 in . Assuming that the stress is constant over the cross-sectional area and if the tension force used is P = 11.0 kips, find the nominal stress experienced by the rod. Determine the force P needed to reach the ultimate stress in the steel-rod specimen.What is unconfined compressive strength test, which triaxial compression test is similar to shows? If the maximum compressive stress value obtained from this test is qu, this test Show the shear strength of the specimen using the Mohr tensile circle.
