Question
Chapter 14, Problem 14.19P
Interpretation Introduction
Interpretation:
The percent increase in the yield strength of pure aluminium, copper and magnesium by strain hardening needs to be determined and compared with each other.
Concept Introduction:
Strain hardening also called as work hardening is a process to strengthen the metal or any polymer by plastic deformation, depending upon the content, the process might be desirable, undesirable or inconsequential. The process gives rise to dislocation generation and dislocation movements within the crystal structure by giving rise to the strength of the material.

A 4-m × 5-m × 6-m room is to be heated by a baseboard resistance heater. It is desired that the resistance heater be able to raise the air temperature in the room from 5 to 25°C within 10 min. Assuming no heat losses from the room and an atmospheric pressure of 100 kPa, determine the required power of the resistance heater. Assume constant specific heats at room temperature. The properties of air are R = 0.287 kJ/kg·K and cv = 0.718 kJ/kg·K (Table A-2a).
The required power of the resistance heater is kW.

- Use PSpice to model the differential amplifier circuit shown in Fig. 4 in DIBO mode (double input balanced output). Use 2N3904 BJTs and use appropriate values for resistors (you can choose the values that will not lead to excessive gain and saturation) to demonstrate that the circuit provides differential amplification.
