The Equation 6.4a and 6.4b using

Answer to Problem 1QAP
The Equation 6.4a and 6.4b using mechanics of materials principles is shown in conclusion.
Explanation of Solution
Write the expression for engineering stress.
Here, the tensile force is P and cross-sectional area is A.
Write the expression for shear stress.
Here, the normal force is P and shear forces is V.
Conclusion:
Show the diagram of a block element of material of cross-sectional area A that is subjected to a tensile force P, the orientations of the applied stress, the normal stress to this plane, as well as the shear stress taken parallel to this inclined plane.
For static equilibrium in the x-direction.
Which means that
Write the expression for the stress
Write the expression for
Thus, the

- We consider a laminar flow induced by an impulsively started infinite flat plate. The y-axis is normal to the plate. The x- and z-axes form a plane parallel to the plate. The plate is defined by y = 0. For time t <0, the plate and the flow are at rest. For t≥0, the velocity of the plate is parallel to the 2-coordinate; its value is constant and equal to uw. At infinity, the flow is at rest. The flow induced by the motion of the plate is independent of z. (a) From the continuity equation, show that v=0 everywhere in the flow and the resulting momentum equation is მu Ət Note that this equation has the form of a diffusion equation (the same form as the heat equation). (b) We introduce the new variables T, Y and U such that T=kt, Y=k/2y, U = u where k is an arbitrary constant. In the new system of variables, the solution is U(Y,T). The solution U(Y,T) is expressed by a function of Y and T and the solution u(y, t) is expressed by a function of y and t.
