Consider a steel (iron) with 0.2 wt% C. Describe the changes in phases and its structure as it is heated under equilibrium conditions to 850 (deg C).
a temperature probe moves with the velocity 2i+2j-3k through air. the temperature of air changes as T(x,y,z,t)=(2x^2-3y+z^3)cos(at). Find the rate of change of temperature measured by the probe.
The electric motor at A exerts a torque of 800N.m on the steel shaft from A to D. This has a torque of -300N.m at B and -500N.m at C. Design specificaions require that the diameter of the shaft be uniform from A to .
