A cylindrical bar of aluminum 19 mm (0.75 in) in diameter is to be deformed elastically by application of a force along the bar axis. Using E=10 psi (Modulus of Elasticity), determine the force that will produce an elastic reduction of 1e-4 in. in the diameter.
How can be determined the dynamic parameters of a second order system, wiht an Inertia (M), a dampening coeficient ( C ) and a Stiffness constant ( K).
Assuming that within metal crystals, the atoms can be considered as hard spheres in contact, sketch arrangement of atoms in a (100) plane, a (110) plane and a (111) plane of face-centered cubic structure. Determine the number of atoms contained wi..
