An FM signal XFM = 2500sin[4π × 108t + 5sin(4π × 106t] with a modulation index of 2.5 is passed through a 1 kΩ resistor. Calculate the: (a) Carrier Frequency
(b) Message Frequency
(c) Signal Power
(d) Bandwidth using the Bessel Table

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

An electric motor is used to drive a power press which makes steel turning moment diagrams 323 pressings from a metal sheet. the motor runs at a mean speed of 50 rev/s. the torque required is 10.0nm for 0.2s, followed by 1.0nm for0.3 s with this sequence then being repeated. what is the minimum power required of the motor and the moment of incrtia required for the t1ywhcel if the speed fluctuations are to be restricted to 1.5%?

Explain the strain-hardening phenomenon on the basis of dislocation - dislocation strain field interactions. also, briefly describe what generally happens to the ductility of a metal that has been strain hardened (i.e. does strain hardening make a metal more ductile or
