The strain rosette shown in the figure was used to obtain normal strain data at a point on the free surface of a machine part. The rosette measures: $\epsilon_a = 1380 \mu \epsilon$; $\epsilon_b = -1270 \mu \epsilon$; $\epsilon_c = 410 \mu \epsilon$; $\nu = 0.21$. (a) Determine the strain components $\epsilon_x$, $\epsilon_y$, and $\gamma_{xy}$ at the point. (b) Determine the principal strains ($\epsilon_{p1} > \epsilon_{p2}$) and the maximum in-plane shear strain $\gamma_{ip}$ at the point. (c) Determine the angle $\theta_p$ (counterclockwise is positive, clockwise is negative), and then draw a sketch showing the angle, the principal strain deformations, and the maximum in-plane shear strain distortions. (d) Determine the magnitude of the absolute maximum shear strain $\gamma_{max}$. $\epsilon_x = -607.5 \mu \epsilon$

A cube of ice is taken from the freezer at -5.5°C and placed in a 85-g aluminum calorimeter filled with 330 g of water at room temperature of 20.0°C. The final situation is observed to be all water at 15.0°C. The specific heat of ice is 2100 J/kg °C, the specific heat of aluminum is 900 J/kg °C, the specific heat of water is 4186 J/kg °C, the heat of fusion of water is 333 kJ/kg. Part A What was the mass of the ice cube? Express your answer to two significant figures and include the appropriate units.

Evaluate the magnitude of the net magnetic force on a current loop of $l_1 = 5.2R$, $l_2 = 3.7R$, and $r = 4.2R$ in an external magnetic field \~$\vec{B} = 8.1B_0(-\hat{j})$ in terms of $B_0$, $R$, $I$. Express your answer using two decimal places. Please note that a current of $3I$ runs on the wire.

The following class declaration is intended to encapsulate the idea of a Player class in a video game, e.g., a first-person-shooter game. class Player{ public: Player(); void heal (int); void damage (int); int getHealth(); private: int health; const int MAX_HEALTH; }; 1. Write the definition of the default constructor of class Player. You should assume the value of MAX_HEALTH will be set to 100 and the health member will be set to the value of MAX_HEALTH..

3. Natural Monopoly Consider a natural monopoly with total cost given by TC = 100 + 10Q (marginal cost is mc = 20 in a market where demand is given by Q = 200 - P). a) Graph the total, average, and marginal cost curves. Why is this a natural monopoly? b) What is the optimal quantity for this market? c) If price is set at marginal cost, what is the quantity traded? Calculate the profits for the monopolist. d) Suppose the government auctions the right to become a monopolist in this market, how much would a firm be willing to pay in this auction if price has to be equal to marginal cost? e) Suppose the price is set at average cost, what is the quantity traded? What are the profits for the monopolist? f) Compare consumer and producer surplus under marginal cost pricing and average cost pricing. g) Is there a price at which the optimal quantity would be traded and firms want to participate in the market? h) Is average cost pricing efficient? Calculate the deadweight loss if there is one. Note: To compute marginal revenue, compute total revenue and take the derivative with respect to Q. For this, consider two rules: (1) Derivative of aQ with respect to Q is a. (2) Derivative of bQ is 2bQ. For example, the derivative of TR = 1000Q - 2Q is MR = 1000 - 4Q. Also, if TR = 1200Q - 2Q^2, MR = 1200 - 2Q.
