ProENGINEER enables its users to create new materials and set multiple properties for them, for example like density, Poisson's ratio, and hardness. But some of these properties are fairly obscure, such as mechanisms damping, tensile strength, coefficient of thermal expansion, and numerous other values. Tier units are also strange, mechanism's damping is expressed in sec/in? Doesn't that sound like the inverse of velocity? And is lbm/(in sec^2) really a measurement of pressure? How is it related to kPa or psi? If anyone can help me with a website with all these values, or can even slightly explain what exactly all this means, I'd greatly appreciate it. Thank you!!
