ay in which the value of fi dependson H is, in its main features, the same for all kinds of iron. For small forces,/A is a constant, for larger forces fx increases, finally it reaches a maximum,and after this decreases in such a way that ultimately fiH approximates toa constant value, known as the… … /A =3000 /i = 2000 /t = I000 The abscissae represent values of H, the ordinate of the thick curve thevalue of nH, and the ordinate of the thin curve the value of ix. The corre-sponding numerical values are as follows: H fiH M H m// M 0-32 40 120 5-17 12680 2450 0-84 170 200 6-20 13640 2200 1-37 420…
