Jump to level 1 Color is a named tuple with fields: name, R, G, and B. Read one string and three integers from input. Create color_data as a Color tuple, and initialize color_data with color_name, red_channel, green_channel, and blue_channel as the fields. - Click here for example ``` from collections import namedtuple Color = namedtuple('rolor', ['name', 'R', 'G', 'B']) l'`' Your code goes here print(f'Color name: {color_data.name}, R: {color_data.R}, G: {color_data.G}, B: {color_data.B}') ```

1. Draw V and M diagrams of the beam shown in Fig. 1. 2. Determine the deformation of the steel rod shown in Fig. 2 under the given loads ($E = 29 \times 10^6 \text{ lb/in}^2$). 3. A simple beam AB of span length $L = 6.7$ m supports a uniform load of intensity $q = 22$ kN/m and a concentrated load $P = 50$ kN. The uniform load includes an allowance for the weight of the beam. The concentrated load acts at a point 2.5 m from the left-hand end of the beam. The beam is constructed of glued laminated wood and has a cross section of width $b = 220$ mm and a height $h = 700$ mm. (a) Determine the maximum tensile and compressive stresses in the beam due to bending. (b) If load $q$ is unchanged, find the maximum permissible value of load $P$ if the allowable normal stress in tension and compression is $\sigma_a = 13$ MPa.

Some experiments in this study used immunohistochemistry with primary antibodies diluted in TBST (10 mM Tris, 167 mM NaCl, and 0.05% (v/v) Tween 20). Using the information below, describe how you would make 500 ml of this solution. Show your working in your answer. [6%] Reagent information: - Molecular weights: - Tris – 121.1 - NaCl – 58.4 - Tween 20 is provided as a 100% solution. b) Once the TBST was made up as above, it was used to dilute three different antibodies, Ab1, Ab2, and Ab3. These three antibodies were used at different concentrations as shown below. Describe how you would make 500 μl of each antibody. Show your working for all calculations. [4%] Antibody dilutions: - Ab1 – 1:500 (i.e., 1 in 500 or 500-fold dilution) - Ab2 – 1:2000 - Ab3 – 1:10000 I think I've calculated the Tween 20 by 0.05%/100 x 500 = 0.25, so 25 ml. But I'm not sure if the question is asking for concentration or not.
