Question
Chapter 60, Problem 1RQ
To determine
The two basic types of transistor.
Expert Solution & Answer
Explanation of Solution
The transistor are the three terminal device that are formed by three pieces of the semiconductor called the emitter, base and the collector. The electron from emitter to base and the recombination takes place. The base is used to provide interaction between the emitter and the collector by controlling the flow of the charges from the emitter to the collector.
The two types of transistor are the NPN and PNP.
The NPN transistor has the collector connected to the positive terminal and emitter to the negative terminal.
The PNP transistor has the collector connected to the negative terminal of voltage supply and emitter is connected to the positive terminal of the voltage supply.
Thus, the two type of transistor are the NPN and PNP.

- Problem 1: Analyze the canard-wing combination shown in Fig. 1. The canard and wing are made of the same airfoil section and have AR AR, S = 0.25, and = 0.45% 1. Develop an expression for the moment coefficient about the center of gravity in terms of the shown parameters (, and zg) and the three-dimensional aerodynamic characteristics of the used wing/canard (CL C and CM). 2. What is the range of the cg location for this configuration to be statically stable? You may simplify the problem by neglecting the upwash (downwash) effects between the lifting surfaces and the drag contribution to the moment. You may also assume small angle approximation.

- An ideal gas with MW of 29 g/mol, cp = 1.044 kJ/kgK and c₁ = 0.745 kJ/kgK contained in a cylinder-piston assembly initially has a pressure of 175 kPa, a temperature of 22°C, and a volume of 0.30 m³. It is heated slowly at constant volume (process 1-2) until the pressure is doubled. It is then expanded slowly at constant pressure (process 2-3) until the volume is doubled. Draw a figure of the system and the PV diagram showing each state and the path each process takes.
