1. (20 points) A bridge is supported by several piers, and the geometry and loads of a typical pier are as shown below. Note that the pier consists of a linearly decreasing, and then linearly increasing, width. 1.0 m 20 kN/m² 0.5 m 2.0 m 1 ① 1.0 m 1.0 m 0.5 m 2 ② 3 The top surface load of 20 kN/m² represents the weight of the bridge and traffic on the bridge. The concrete weighs 30 kN/m³ and the modulus is E = 28 × 10⁶ kN/m². We will model this pier as a 1-D structure, using a 3-node, 2-element discretization as shown in the figure. Recall that for each element, the finite element matrix equation is of the form: [K] [u] = [fe] + [Q] We are using the linear Lagrange interpolation functions in this finite element model. For this finite element discretization, derive K₁₁ and f₁. i.e., for Element 1, derive the K₁₁ entry of the stiffness matrix and the f₁ entry of the RHS force vector.

PART B 9 a) A horizontal continuous beam $ \mathrm{ABCD} $ consists of three equal spans $ \mathrm{AB}, \mathrm{BC}, \mathrm{CD} $ of length $ 3 \mathrm{~m} $ each. End spans (AB and CD) carry a UDL of $ 30 \mathrm{kN} / \mathrm{m} $ each and middle span has a concentrated load of $ 60 \mathrm{kN} $ at centre. If the support $ B $ settles by $ 2 \mathrm{~mm} $, find out the support moments. Take $ \mathrm{I}=2 \times 10^{8} \mathrm{~mm}^{4} $ and $ \mathrm{E}=250 \mathrm{kN} / \mathrm{m}^{2} $.

Figure 1: Schematical structure of a simplified c-Si solar cell. ?=600 nm nAir=1 n-type d=220 µm nsj=3.94+i0.02 p-type nAir=1 Figure 1 shows a simplified c-Si solar cell at room temperature T = 300 [K]. The cell is illuminated under normal incidence, by a monochromatic light source with a wavelength of ? = 600 [nm] and photon flux ? (600nm) = 4.46 \cdot 10^{18} [m^{-2}s^{-1}]. For simplicity's sake, we will treat the p-n junction as a single absorber layer during the optical calculations, with a thickness of d = 220 [µm] and complex refractive index $\tilde{n}_{Si}$ (600nm) = 3.94 + i0.02. The cell is surrounded by air, which has a refractive index of $n_{air}$ = 1. The cell has a saturation current density of $J_0 = 5.5 \cdot 10^{-12}$ [A m$^{-2}$]. A) We will now calculate the so-called R-T-A data of this solar cell, to gain insight into its optical performance. What fraction of the incident light is reflected of the front surface (R), absorbed in the c-Si absorber (A) and transmitted from the back of the cell (T)? Give a percentage [%] R T A B) We assume that all aborbed photons generate one electron-hole pair. What is the generated photocurrent in [A m$^{-2}$]? Give the answer in two decimal numbers. C) Calculate the open-circuit voltage $V_{OC}$ in [mV].
