A solid copper cube has an edge length of 85.5 cm. How much stress must be applied to the cube to reduce the edge length to 85.0 cm? The bulk modulus of copper is 1.4 Times 10^11 N/m^2.
A cube of proper edge length ( and mass m is moving past you at speed 0.8c. Determine the volume for the object that you observe if the velocity is directed (a) along an edge, (b) along a face diagonal, and (c) along the body diagonal of the cube. Note: The body diagonal is difficult. What density do you observe the cube to have in each situation How do these densities compare to nuclear densities? At what speed wll the...
