Consider a series RLC circuit with a resistor R = 51.0 Ω, an inductor L = 2.20 mH, a capacitor C = 0.0722 µF, and an AC source that provides 0.155 volts RMS at 25.8 kHz (kilohertz). What is the impedance (ohms) of the circuit? (State answer as a whole number with no decimal).

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
