In the single-phase full-wave bridge rectifier, if vs = 220sin2π60t , Rd=11 Ω , Ld = 11 mH Determine: a. The average (DC) output voltage and current in the load. b. The AC components of output voltages up to the fourth harmonic in the load. c. The active power absorbed by the load and the power factor.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false
