(b) now consider the scattering of a small projectile off a hard "sphere" (actually a hard disk) of radius r pinned down to the ice. find the differential cross section. (note that in two dimensions, hard "sphere" scattering is not isotropic.) (c) by integrating your answer to part (b), show that the total cross section is 2r as expected.

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.

What is the main objective of using reheat rankine cycle?

Analyze the factors that influence the choice between the following pairs of processes to make the products indicated: i) sand casting versus die casting of an electric-motor housing ii) thread rolling versus machining of a bolt for high-strength application. (co3/c5)
