It is known that a rectangular cross section of a reinforced concrete beam with beam width b = 300 mm and beam height h = 550 mm, concrete quality 42 Mpa and steel quality 420 Mpa, modulus of elasticity of steel 200,000 Mpa. Assume the effective height of the beam is d = 500 mm. If the beam section is analyzed as a section with single reinforcement (M+/reinforcement below): 1. Determine the amount of reinforcement area required to achieve the balanced condition and the nominal moment at the balanced condition, then the nominal moment if the ratio of reinforcement under under-reinforced condition is 0.75 times of the reinforcement value in balanced condition. 2. Determine the nominal moment if the ratio of the reinforcement in the over-reinforded condition is 1.25 times the area of ​​the reinforcement in the balanced condition, then draw a strain diagram depicting the three conditions with each of the reinforcement areas. Write down the magnitude of the strain value and the distance c from the neutral line on the diagram, respectively. What is the stress on the steel reinforcement for each of the above conditions. Determine the approximate amount of reinforcement for the section in problem no. 1 and 2. The diameter of reinforcement that can be used is D-10, D-13, D-16, D-19, and D-22. Draw the cross section and the amount of reinforcement.

A student determines the mass percent of iron in a sample of iron ore by doing a redox titration. The student finds the mass of the sample and then dissolves it in acid to a total volume of 25.00 mL. Using a buret, the student titrates the 25.00 ml solution with 0.017 M K,C1,07. The following reaction occurs during the titration. Cr,0,? (aq) + 6 Fe2+ (aq) + 14 11+ (aq) + 2 Cr3+ (aq) + 6 Fe (aq) + 7 H1,0(1) The student collects the following data Mass of iron ore in original sample Buret reading at end point 0.36 g 45.52 mL 15.05 mL Initial buret reading (a) How many moles of Fe2+ (aq) reacted with the Cr, 0,2- (aq)?

(b) Assuming that all the iron in the ore was fet calculate the mass percent of iron in the ore sample. B I U x? X2 C 12 0/10000 Word Limit ©) The student learns that the actual mass percent of iron in the ore sample is greater than the experimental value calculated in part (b). The student claims that the difference between the actual and experimental values could have been caused by rinsing the buret with distilled water just prior to filling it with 0.017 M K,Cr,0(aq). Do you agree with the student's claim? Explain your reasoning. В І x X2 5 Ω Ee
