E.2 use the voltage divider rule to find the transfer function vo(s)/vi(s) of the circuit in fig. e.3(a). show that the transfer function can be made independent of frequency if the condition c1r1 = c2r2 applies. under this condition the circuit is called a compensated attenuator. find the transmission of the compensated attenuator in terms of r1 and r2.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.

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.
