- Write a note on toughness mechanism in brief. What is the standard size of square and round test specimen? Which property of material can be determined by impact test? Why friction loss test is conducted in impact test experiment? What is the difference between charpy impact test and izod impact test?What is period of deformation?(Suppose you need to design a tension test machine capable of testing specimens that have nominal ultimate stresses as high as σu = 100 ksi . How much force must the machine be capable of generating? Assume the testing specimen has the ASTM shape shown. Answer for this is 19.6 kip) (If the maximum nominal strain is ϵf = 0.7 just before the test specimen fractures and the test machine operates by moving only one grip, how far must that grip be designed to travel? The total length of the deforming part of the specimen is 3 in. Answer for this is 2.10 in) Do not know if this info is needed but this was the other 2 parts
