Refer to the phase diagram and figures below and identify the microstructure that corresponds to 50wt% Sn- 50wt%Pb at 150°C

The International Space Station is orbiting at an altitude of about 370 km above the earth’s surface. The mass of the earth is 5.97 × 1024 kg, the radius of the earth is 6.38 × 106 m, and G = 6.67 × 10-11 N ∙ m2/kg2. Assume the orbit is circular. (a) What is the period of the International Space Station’s orbit? (b) What is the speed of the International Space Station in its orbit? (c) The ISS has a mass of approximately 4.45 × 105 kg. Calculate the total mechanical energy of the ISS in its orbit.

Consider a metal single crystal oriented such that the normal to the slip plane and the slip direction are at angles of 60° and 35°, respectively, with the tensile axis. If the critical resolved shear stress is 7 MPa, will an applied stress of 13 MPa cause the single crystal to yield? If not, what stress will be necessary?
