Given the spectrum X(f) of an analog signal x(t), sketch the spectrum of its sampled version x[n], assuming a sampling rate of 50, 40, and 30 Hz. (a) X(f) = rect(f/40)

(b) X(f) = tri(f/20)

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.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
