آموزش مکانیک محیطهای پیوسته

سلام کسی محیط پیوسته ی chang رو نداره؟

[ali bohlooli 10]

[A motion of a fluid is given by the equations

x_1=X_1+X_2t+X_3 t^2

x_2=X_2+X_3t+X_1 t^2

x_3=X_3+X_1t+X_2 t^2

Find the velocity and acceleration of: (a) the particle which was at the point (1, 1, 1) at the reference

time t = 0, and (b) the particle which occupies the point (1, 1, 1) at time t. Explain why this motion

becomes physically unrealistic as t → 1.
