(a) Equations 6.4a and 6.4b are expressions for (a) Equations 6.4a and 6.4b are expressions for normal (s’) and shear (t’) stresses, respectively, as a function of the applied tensile stress (s) and the inclination angle of the plane on which these stresses are taken (? of Figure 6.4). Make a plot on which is […]

The input impedance of a 31-cm-long lossless transmission line

The input impedance of a 31-cm-long lossless transmission line The input impedance of a 31-cm-long lossless transmission line of unknown characteristic impedance was measured at 1 MHz. With the line terminated in a short circuit, the measurement yielded an input impedance equivalent to an inductor with inductance of 0.064 ÂľH, and when the line was […]
