Stepped bar ABC is fabricated out of aluminum and supported by a fixed support at C as shown. The cross-sectional area of step AB is $A_{AB} = 2.5 \text{ in}^2$ and the cross-sectional area of step BC is $A_{BC} = 3.5 \text{ in}^2$. Determine the normal stress in steps AB and BC and the total deformation of the stepped bar under the applied forces. Take $F_A = 7.5 \text{ kips}$, $F_B = 4 \text{ kips}$, $L_{AB} = 12 \text{ in}$, and $L_{BC} = 16 \text{ in}$. $\sigma_{AB} = 3 \text{ ksi}$ $\sigma_{BC} = 1.167 \text{ ksi}$ $\delta_{ABC} = 0.0052 \text{ in}$

15. Solar water-splitting is extensively explored as a promising alternative source of renewable energy (Cho, J., et al. Acc. Chem. Res. 2019, 52, 645-655). This fossil fuel-independent technology involves solar light harvesting and the redox reaction of water to produce energy-dense fuels, H2, and O2: H2O(l) → H2(g) + 1/2O2(g); ΔΗrxn = +286 kJ How much heat is evolved when 27.1 g O2 (M = 32.00 g/mol) is produced? a. +121 kJ b. +484 kJ c. +1.52 kJ d. +242 kJ

2. The boiling point of a pure liquid is a reflection of the intermolecular forces (IMFs) that are present. The types of IMFs are dispersion forces, dipole-dipole interactions, & hydrogen bonding. Below are three liquids. Identify the IMFs present in each. Based on the IMFs present in each, predict the ranking of pure liquids from highest to lowest vapor pressure.
