Q1: A specimen made from Titanium with diameter 4 mm subjected to force of 2500 N. The specimen extended by 0.422 mm. If the young modulus is 107 GPa. Find the gauge length of specimen.
In a forming process the diameter of the specimen is 1 cm and its length changes from 50 mm to 60 mm. Show the maximum force value on the graph of Force vs. True Strain plotted in Excel Program or any plotting program not by hand using the flow stress equation given below. σ= Kεn and σ=F/A Where the parameters are σ : True Stress in MPa K: Strength Coefficient, K=210 in MPa ε : True Strain, ε=ln (l/l0) n: Strain Hardening Exponent, n=0.27 F: Force in 10 A : Area in mm2 Take at least 3 digits after the decimal point. Specify the units. You can use Excel or any plotting program not by hand then paste your graph into the solution section.

6. State your answers to the following questions.Strain Gauge represents the deformation of a material through a change in resistance. If so, explain how temperature will affect the strain gauge in the experimental environment.①:In this experiment, the Strain Gauge measures the strain in micro units. Explain one possible error factor when applying a load by hanging a weight on the material with the strain gauge attached. (Hint: It is easy to shake by hanging the weight using a thread)①:
1. A tension test on an aluminum plate resulted in the following engineering stress-engineering strain data as reported in the first and second column of the table below (reduction of area, RA=17%): S (psi) e (in/in) σ (psi) ε (in/in) 10500 0.001 10510.5 0.000995 21000 0.002 31200 0.003 41300 0.004 51200 0.005 61200 0.006 70600 0.007 74700 0.0075 76800 0.008 77600 0.0085 78000 0.009 78400 0.0095 78700 0.01 81200 0.02 83000 0.03 84200 0.04 85400 0.05 86200 0.06 86800 0.07 *87200 0.08 **86200 0.1 Note: * maximum load, ** load at fracture a) Calculate the corresponding true stress and true strain and give your results in a table along with the engineering stress, engineering strain shown in the of table above (column 3 and 4). b) Plot the true stress-true strain curve on a rectangular coordinate. c) Plot the true stress-true strain curve on a log-log graph and determine the plastic flow curve parameters K and n, the yield strength, Y, and the elastic modulus, E of the material.
the material had a tensile stress of 67.7 ksi then was unloaded. the original length of the specimen was 5.0 inches. show the line on the diagram you would expect the material to follow as the load was released. estimate the length of the specimen after all load was removed.
5- B) What do you mean by strain? A strain gauge has a resistance of 157.4 ohms and a gauge factor of 2.7. Find the change in resistance of the gauge for a strain of 0.0017.
1-A round member having a diameter of 3cm experience an axial load of 10KN. Two strain gauges are mounted on the member, one measuring an axial strain of 600 micro-strain and the other measuring a lateral strain of -163 micro-strain. The modulus of elasticity in GPa is Choose... The Poisson ratio is Choose... + The stress in MPa is Choose... + Next page
1. The table shows the results of a tensile test with a sample with a cross-sectional area of 100 mm2 and an initial length of 100.000 mm. (1) Plot the data as engineering stress versus engineering strain. Use the standard unit [Pa] or [MPa]. (2) Determine the modulus of elasticity and the yield strength at a strain offset of 0.002.
