b) An I-beam made of 4140 steel is heat treated to form tempered martensite. It is then welded to a 4140 steel plate and cooled rapidly back to room temperature. During use, the I-beam and the plate experience an impact load, but it is the weld which breaks. What happened?
a. which one has a better stiffness? gold or tungsten?
b. which one is more ductile? low carbon steel or high carbon steel?
Q/ Define the stiffness? Discuss the criteria for selection of materials
for stiffness
