A symmetrical wedge having a total vertex angle of 60 degrees is
traveling at a Mach number of 3 at an altitude of 15 km. What are
the static values of the pressure, density, and temperature
downstream of the shock, and what are the stagnation values of
those quantities? What is the percentage loss of the stagnation
pressure across the shock wave?
. Light travels at different speeds through materials due the
refractive index of that material. Given that I have a transparent
polymer material, would light travel faster or slower through it if
it (a) have zero stress on it or (b) have a substantial, but still
elastic, stress on it (say 20 MPa for HDPE)? Explain.
