A gear-and-shaft system is shown below. Shaft AB (length $L_{AB}$ = 12 in) is the input shaft and Shaft CD (length $L_{CD}$ = 15 in) has a fixed end. Both shafts are the same diameter and are made of a material with G = 5x$10^6$ psi. Gear B has radius $r_B$ = 4 in and Gear C has radius $r_C$ = 5 in. A torque T = 450 lb-in is applied at end A. If the allowable shear stress of the shafts is 7 ksi and the allowable rotation of A is $7^\circ$, what is the smallest allowable radius of the shafts? D $L_{CD}$ $r_C$ $r_B$ B C $L_{AB}$ A T

13 Example 3.10 with some modifications-Two tanks are connected by a valve. One tank contains 2 kg of carbon monoxide gas (CO) at T=77 °C and P=0.7 bar. The other tank holds 8 kg of the nitrogen gas (N2) at T=27 °C and P=1.2 bar. The valve is opened and the gases are allowed to mix while receiving energy by heat transfer from the surroundings. The final equilibrium temperature is T_{final} =42 °C. Using the ideal gas model with constant $C_v$, determine (a) the final equilibrium pressure, $P_{final}$, in bar, (b) the heat transfer (Q) for the process, in kJ.
