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.

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
