Ordinary sheets of borosilicate glass are tested in bending, and are found to fracture at an average stress of 72 MPa. After thermal tempering, the stress at failure increases by 90%. What are the sign and magnitude of the stress induced in the glass by the tempering operation?
The lower yield point for a certain plain carbon steelbar is found to be 135 MPa, while a second bar of the samecomposition yields at 260 MPa. Metallographic analysisshows that the average grain diameter is 50μm in the firstbar and 8μm in the second bar.a. Predict the grain diameter needed to cause a loweryield point of 205 MPa.b. If the steel could be fabricated to form a stablegrain structure of 500 nm grains, what strengthwould be predicted?c. Why might you expect the upper yield point to bemore alike in the first two bars than the lower yieldpoint?
: During tensile tests, strain hardening was observed for a metal alloy with a tensile strength
of 18,000 psi under regular yielding condition. However, when it was pre-stretched to a 0.5% extension
(based on the initial length of the specimen), its strength increased to 20,000 psi. If the pre-extension is
increased to 5%, what could be the strength of the material?

- I did a torsion test to experimentally calculate the brass modulus of rigidity. My experimental modulus value is lower than the published. What could have caused this?arrow_forwardA three-point transverse bending test was performed on a glass specimen having a square cross-section of 18.5 mm length on each edge. The specimen fractured at a load of 4530 N when the distance between support points was 42 mm. A second test is to be performed on another specimen of this same glass material, but one that has a circular cross-section. What minimum specimen diameter is required to ensure that fracture will not occur when a load of 3480 N is applied? Assume that the support separation is maintained at 42 mm. mmarrow_forwardA cylindrical brass rod with a minimum tensile strength of 450 MPa, a ductility of at least 13% EL (elongation), and a final diameter of 12.7mm is required. You have in your inventory some 19.0mm diameter brass stock that has been cold worked to 35%. Assuming that the cross section of the rod is still circular after being cold worked, and that brass experiences cracking at 65% CW, describe the necessary working steps in order to achieve the final product. Take the expression for % cold work to be = (Ao - Af)/ Ao x 100%, where Ao and Af are the original and final circular cross-sectional areas of the rod.arrow_forward
