blem 1. For mixing two components of a non-ideal solution together (A and B) g a model 2-D square array, the expression for AG is given in eqn. 7.38. mixing (A) Derive the expression for the derivative of this expression with respect to XA (i.e., d(AGming) / dx ). (B) Using separate Excel plots, plot both AGig and d (AGing ) / dx, for xA = 0.100 to 0.900 in 0.025 increments at T = 298.15 K for three different values of Aɛ: 520, 620, 720 J/mole. Do not hand draw these plots but include copies of your actual Excel plots

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.
