The 80-kg ventilation door OD with mass center at G is held in the open position shown by means of a moment M applied at A to the opening linkage. Member AB is parallel to the door for the $30^{\circ}$ position shown. Determine M.

A flow calorimeter is a device used to measure the specific heat of a liquid. Energy is added as heat at a known rate to a stream of the liquid as it passes through the calorimeter at a known rate. Measurement of the resulting temperature difference between the inflow and the outflow points of the liquid stream enables us to compute the specific heat of the liquid. Suppose a liquid of density $0.85 \mathrm{~g} / \mathrm{cm}^3$ flows through a calorimeter at the rate of $8.0 \mathrm{~cm}^3 / \mathrm{s}$. When energy is added at the rate of $250 \mathrm{~W}$ by means of an electric heating coil, a temperature difference of $15 \mathrm{C}^{\circ}$ is established in steady-state conditions between the inflow and the outflow points. What is the specific heat of the liquid?

Open Door Manufacturer earned $100,000 this year. The company follows the residual dividend policy when paying dividends. Open Door has determined that it needs a total of $120,000 for investment in capital budgeting projects this year. If the company's debt-to-asset ratio is 50 percent, what will its dividend payout ratio be this year?

If you leave me refrigerator door open and the refrigerator runs continuously, does the kitchen get colder or warmer? Explain.

A point source with volume flow Q = 30 m³/s is immersed in a uniform stream of speed 4 m/s. A Rankine half-body of revolution results. Compute (a) the distance from source to the stagnation point and (b) the two points (r, θ) on the body surface where the local velocity equals 4.5 m/s.

Solve previous problem for the case where the assembly starts from rest with an initial angular acceleration $\alpha=900 \mathrm{rad} / \mathrm{s}^{2}$ as a result of a starting torque (couple) M applied to the shaft in the same sense as N. Neglect the moment of inertia of the shaft about its z-axis and calculate M.

Manganese is available from its ore pyrolusite, which is manganese(IV) oxide, $\mathrm{MnO}_2$. Some manganese metal is prepared from $\mathrm{MnO}_2$ by reduction with aluminum metal. Write the balanced equation for this reduction.

Compute the deoxygenation rate constant and reaeration rate constant (base e) for the following wastewater and stream conditions.

$$\begin{matrix} \text{ } & \text{k} & \text{Temperature} & \text{H} & \text{Velocity} & \text{ }\\ \text{Source} & \ {\left(\mathrm{day}^{-1}\right)} & \ {\left(^{\circ} \mathbf{C}\right)} & \text{(m)} & \ {\left(\mathbf{m} \cdot \mathbf{s}^{-1}\right)} & \ {\eta}\\ \text{Wastewater} & \text{0.20} & \text{20} & \text{ } & \text{ } & \text{ }\\ \text{Amaunet Stream} & \text{ } & \text{20} & \text{3.0} & \text{0.5} & \text{0.4}\\ \end{matrix}$$

A cylindrical pressure vessel having a radius $r=14\ \text{in.}$ and wall thickness $t=0.5\ \text{in.}$ is subjected to internal pressure $p=375\ \text{psi}$. In addition, a torque $T=90\ \mathrm{kip}- \mathrm{ft}$ acts at each end of the cylinder. (a) Determine the maximum tensile stress $\sigma_{\max }$ and the maximum in-plane shear stress $\tau_{\operatorname{mix}}$ in the wall of the cylinder. (b) If the allowable in-plane shear stress is $4.5\ \mathrm{ksi}$, what is the maximum allowable torque $T$ ? (c) If $T=150\ \mathrm{kip-ft}$ and allowable in-plane shear and allowable normal stresses are $4.5\ \mathrm{ksi}$ and $11.5\ \mathrm{ksi}$, respectively, what is the minimum required wall thickness?
