Question 3 [7+7+7 = 21 pts]. A cylindrical geometry under combined loading Consider a solid round long slender bar with one end fixed and more than one type of load acting on the other end, as shown in Figure 2. a) Consider only the axial force F (along the z-axis in a cylindrical coordinate system) and the torsion/twisting torque T are acting on it (no bending moment). Write the 3D stress tensor for material points at the outermost fibers and the material points at the central axis using a cylindrical coordinate basis {êr, êe, êz}. b) Consider only the axial force F (along the z-axis in the cylindrical coordinate system) and bending moment M (in the plane of the paper) are acting on it (no torsion). Write the 3D stress tensor for material points at the outermost fiber at the very bottom considering {êr, êe, êz} coordinate basis. c) For a point at the outermost fiber at the very bottom, write the 3D stress tensor when all three axial force F, torsional moment T, and bending moment M are acting.

2) Consider the circuit shown in Figure 2. $4mA$ $2k\Omega$ $2mA$ $1k\Omega$ $1k\Omega$ $1k\Omega$ $1mA$ $2k\Omega$ + $V_o$ - Figure 2. Circuit for Problem 2. a) Find $V_0$ using the node voltage method. b) Verify your by-hand answer for $V_0$ LTSpice. Write out the answer you got from LTSpice and attach any supporting evidence that you actually simulated the circuit to verify your work. The answer you write out for this part should be the same as the result you provided in part (a); if it doesn't match by both sign and magnitude, expect zero credit. Also, expect zero credit 1) if your by-hand and simulated results agree but the results are incorrect, 2) if you do not perform the LTSpice verification altogether, 3) if you only do the LTSpice verification but not the by-hand solution, or 4) if you do not label the voltage nodes and have LTSpice compute the value of $V_0$ for you.

6. A unit-speed parametrization of a circle may be written $\gamma(s) = c + r \cos\left(\frac{s}{r}\right)e_1 + r \sin\left(\frac{s}{r}\right)e_2,$ where $e_i \cdot e_j = \delta_{ij}$. If $\beta$ is a unit-speed curve with $\kappa(0) > 0$, prove that there is one and only one circle $\gamma$ that approximates $\beta$ near $\beta(0)$ in the sense that $\gamma(0) = \beta(0)$, $\gamma'(0) = \beta'(0)$, and $\gamma''(0) = \beta''(0)$. Show that $\gamma$ lies in the osculating plane of $\beta$ at $\beta(0)$ and find its center $c$ and radius $r$ (see Fig. 2.13). The circle $\gamma$ is called the osculating circle and $c$ the center of curvature of $\beta$ at $\beta(0)$. (The same results hold when 0 is replaced by any number $s$.)
