Free Body Diagram

The system of forces acting on a body tends to either rotate it or make the body undergo motion. In general, when an external agent exerts a force on a body, the body undergoes translational motion and rotational motion. The body has six degrees of freedom under the influence of that force. Here, three degrees of freedom are from the translational motion while the other three are from the rotation motion. However, sometimes the bodies are not allowed to undergo any motion and are fixed, under such conditions the body is said to be constrained.

QUESTION 5 Using the continuous-cooling transformation diagram for a eutectoid Fe-C alloy shown below, perform the following tasks. (a) Plot the cooling curve (rough position) corresponding to normalising treatment, and specify the microstructure obtained. (b) Plot the cooling curve (rough position) corresponding to full annealing, and specify the microstructure obtained. (c) Design a heat treatment to produce a duplex microstructure of about half pearlite and half tempered martensite, specifying all the steps and plotting, roughly, the cooling curve involved. (d) If a full (i.e. 100%) tempered martensitic microstructure is desirable, describe the conditions for achieving it in terms of both cooling rate and sample size. (e) What treatment do you propose to do if a fully annealed steel is still too hard for processing (e.g. forging)? Plot the microstructure after such a treatment, marking any dimension that is important.
