Solved in 2 steps
- The (G-E) diagram obtained in the tensile test performed on a metal sample with a diameter of 16 mm is as follows. The loads at points A, B and C and the elongation measured on l. 16 cm gauge length were determined as follows: B A B C Load (kgf) 4800 8400 7200 Elongation (mm) 0.192 28.8 38.4 c) Calculate the fracture work and the maximum elastic energy the metal rod can store. d) Find the cross-sectional area of a 6 m long rod made of this metal such that it can carry 12 tons of load with 2 times the safety of yield strength. How long does the rod extend under this load?Relative hardness is measured on Moh's scale. True FalseQuestion 22 What is the advantage of bonding tabs to the ends of the FRP specimen when conducting tensile test? Use the editor to format your answer
- please send me a solution in detail. Thanks in advanceShow the complete and organize solution. Write your answer with four decimal places and enclose them in a box. Solve as neatly as possible thank you! ANSWER ONLY A AND Ba. Calculate the ductility of the sample as a percentage (%) b. Calculate the stress required to create a neck in the sample, in MPa.
- i need the answer quicklyA 13 mm diameter tensile specimen has 50 mm gauge length. If the load corresponding to the 0.2% offset is 6800 kg, the yield stress will be nearly 1. 31 kg/mm² 2. 43 kg/mm² 3. 51 kg/mm² 4. 63 kg/mm² XThe results of a tensile test are shown in Table 1.5.2. The test was performed on a metal specimen with a circular cross section. The diameter was 3 8 inch and the gage length (The length over which the elongation is measured) was 2 inches. a. Use the data in Table 1.5.2 to produce a table of stress and strain values. b. Plot the stress-strain data and draw a best-fit curve. c. Compute the, modulus of elasticity from the initial slope of the curve. d. Estimate the yield stress.
- A ceramic sample with a rectangular section can support a load of up to 290 N under a common strength test for ceramics. Its flexural strength is then 78.3 MPa and the distance between support points is 45 mm. What would be the dimensions of this sample if its width were twice its height?During tensile testing, you forgot to measure the change in the longitudinal dimension of the sample. However, you have managed to measure change in the cross-sectional area with time. With this information alone, will you be able to estimate the true strain exhibited by the material at a given time t. How accurate would such estimation be?1. A vertical pressure of 70 MPa is applied to an aluminum cube sample with a length of 10 cm on each side. The modulus of elasticity of aluminum is 70000 MPa and the Poisson ratio is 0.3. a) Find the new dimensions of the cube b) What will be the new dimensions if 70 MPa pressure is applied in the horizontal directions in addition to the 70 MPa pressure in the vertical direction?
