For a brass alloy, the following engineering stresses produce the corresponding plastic engineering strains, prior to necking: On the basis of this information, compute the engineering stress necessary to produce an engineering strain of 0.25.How much will a specimen of this material elongate if the original length is 300 mm

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.
