The figure below shows a section of hot-water pipe consisting of three parts: a straight, horizontal piece h = 28.0 cm long, a straight vertical piece f = 120 cm long, and an elbow joint that allows the two pipe sections to meet at a right angle. A stud and a second-story floorboard hold the ends of this section of pipe stationary. The pipe is made of a copper alloy with a coefficient of linear expansion of 1.7 \times 10^{-5} (\text{°C}^{-1}). When the water flow is turned on, the temperature of the pipe rises from 18.0°C to 44.9°C. What is the magnitude and direction of the displacement of the pipe elbow from its original location once the pipe reaches the higher temperature? (Give the magnitude in mm and the direction in degrees below the +x-axis, which is parallel to the horizontal piece, and points from the stud to the elbow joint.) magnitude mm direction °

5.13 Develop a formal proof of correctness for alpha-beta pruning. To do this, consider the situation shown in Figure 5.18. The question is whether to prune node $n_j$, which is a max-node and a descendant of node $n_1$. The basic idea is to prune it if and only if the minimax value of $n_1$ can be shown to be independent of the value of $n_j$. a. Mode $n_1$ takes on the minimum value among its children: $n_1 = min(n_2, n_{21}, \dots, n_{2b_2})$. Find a similar expression for $n_2$ and hence an expression for $n_1$ in terms of $n_j$. b. Let $l_i$ be the minimum (or maximum) value of the nodes to the left of node $n_i$ at depth $i$, whose minimax value is already known. Similarly, let $r_i$ be the minimum (or maximum) value of the unexplored nodes to the right of $n_i$ at depth $i$. Rewrite your expression for $n_1$ in terms of the $l_i$ and $r_i$ values. c. Now reformulate the expression to show that in order to affect $n_1$, $n_j$ must not exceed a certain bound derived from the $l_i$ values. d. Repeat the process for the case where $n_j$ is a min-node.

Determine the transfer function for each mass shown below in terms of Xi/F (i = 1, 2, 3). Once determined, plot the time-response behavior of each mass, on the same plot. The deliverable for this problem will be the hand-written work (8 pts) followed by a plot of the displacements of each mass (all on the same plot) over a range of 25 seconds (1 pt), followed by the code you used to create the plots (should be part of the pdf file) (1 pt). $M_1 = 10 \text{ kg}$ $M_2 = 40 \text{ kg}$ $M_3 = 35 \text{ kg}$ $k_1 = 10 \text{ N/m}$ $k_2 = 75 \text{ N/m}$ $c_1 = 15 \text{ N-s/m}$ $c_2 = 25 \text{ N-s/m}$ $c_3 = 15 \text{ N-s/m}$ $f(t) = 7\cos(4t)$
