A body moves through standard air at 200 m/s. What is the stagnation pressure on the body? Assume (a) compressible flow and (b) incompressible flow.
a 13.2-N force P is applied to the lever which controls the auger of a snowblower. Determine the moment of P about A when alpha is equal to 30 degrees.
Niobium forms a substitutional solid solution with vanadium. Compute the weight percent of niobium that must be added to vanadium to yield an alloy that contains 1.55 x 1022 Nb atoms per cubic centimeter. The densities of pure Nb and V are 8.57 an..
Fireclay brick of dimensions 0.06 m x 0.09 m x 0.20 m is removed from a kiln at 1600 K and cooled in air at 40oC with h=50 W/m2/K. What is the temperature at the center and at the corners of the brick after 50 minutes of cooling?
