What is the carbon concentration of an iron-carbon alloy just below the eutectoid for which the fraction of total ferrite is 0.70? The iron-iron carbide phase diagram is shown in the Animated Figure 9.24.

Apipe with an outside diameter of 15 cm is exposed to an ambient air and surrounding temperature of -20°c. the pipe has an outer surface temperature of 65°c and an emissivity of 0.85. if the rate of heat loss from the pipe surface is 0.95 kw per meter of length, the external convective heat transfer coefficient (h) is: (a) 12.5 w/m"k (b) 18.6 w/mk (c) 23.7 w/mk (d) 27.9 w/mk (e) 33.5 w/mk

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.
