2. ### A steel plate 2 cm thick is maintained at a temperatur

Hi A steel plate 2 cm thick is maintained at a temperature of 550 C at one face and 50 C on the other . The thermal conductivity of stainless stress at 300 C is 19.1 W/mK . Compute the heat transferred through the material per unit length ? Answer : - we have q = - k . A . (dt/dx) now...
3. ### A solid steel shaft is subjected to a torque of 45 KN/m.

A solid steel shaft is subjected to a torque of 45 KN/m. If the angle of twist is 0.5 degree per meter length of the shaft and the shear stress is not exceed 90 MN/m^2 (I) find the suitable diameter of the shaft . Take C = 80 GN/m^2 (II) Maximum shear strain we can solve the question by...
