Richard owned a rental home with an $85,000 fair market value, a $70,000 adjusted basis, and a $60,000 mortgage. He initiates a like-kind exchange with Ramos. Ramos gives Richard $12,000 in cash plus a rental property with a $65,000 fair market value ($50,000 basis) and a $52,000 mortgage. For this problem, just state who the boot receiver is and how much the boot is.

2a) Using the free electron model, and denoting the electron concentraion by n, show that the radius of the Fermi sphere in k-space is given by k_F = (3\pi^2 n)^{1/3} b) As the electron concentration increases, the Fermi sphere expands. Show that this sphere begins to touch the faces of the first zone in an fcc lattice when the electron to atom ratio n/n_a = 1.36, where n_a is the atom concentration. c) Suppose that some of the atoms in a Cu crystal, which has an fcc lattice, are gradually replaced by Zn atoms. Considering that Zn is divalent while Cu is monovalent, calculate the atomic ratio of Zn to Cu in a CuZn alloy (brass) at which the Fermi sphere touches the zone faces. Use the free electron model. (Omar 5.14) Notes: \begin{itemize} \item This particular brass is interesting because the solid undergoes a structural phase change at this concentration ratio. \item The attached page from Kittel may help you visualize the BZ for a fcc lattice. \item If one were to use a nearly free electron model, the fermi surface distorts wherever it gets near the zone boundary (as we have seen in class for 1-dimensional systems). This produces strange looking \"necks\" in the Fermi surface, as the back of the sheet shows. \end{itemize}

Q1 A mechanical press is powered by a 30-hp motor and operates at 40 cycles per minute. It uses a flywheel so that the rotational speed of the crankshaft does not vary appreciably during the cycle. If the distance the hammer moves is 6 in., what is the maximum contact force that can be exerted over the entire cycle length? Q2. For the above press to what height can a 6061 -O aluminum cylinder be forged before the press stalls?
