3. The I-beam below is comprised of three plates welded together. The top and bottom flanges are 10 mm $\times$ 200 mm in cross-section and the web is 8 mm $\times$ 150 mm. (a) Neatly plot the shear force and bending moment diagrams for the following beam. Indicate all values of bending moment and shear force at critical points. (b) Calculate the normal stress due to bending at point A in the beam. Point A is located 20 mm from the bottom of the section (i.e., 10 mm above the web-flange junction). (c) Calculate the shear stress at point A. (d) Neatly draw the “state of stress” (i.e., the stress element) at point A. Built-Up Beam: w = 500 kN/m A 20 mm 400 mm 1600 mm

Answer the questions for the function f(x) = 4x^4 - 48x^3 a. Find formulas for f'(x) and f''(x). f'(x) = 16x^3 - 144x^2 f''(x) = 48x^2 - 288x Enter f(x), f'(x), and f''(x) into your grapher to examine the table. b. Set f'(x) = 0 to find the critical numbers. One of the critical numbers of f(x) is x = 0. What is the other critical number? x = 9 What is true about f(x) at this positive critical number? Select the correct choice below and, if necessary, fill in the answer boxes within your choice. A. The graph of f is concave up and f has a relative maximum at ( , ). B. The graph of f is concave up and f has a relative minimum at ( , ). C. The graph of f is concave down and f has a relative maximum at ( , ). D. The graph of f is concave down and f has a relative minimum at ( , ). E. No conclusion can be made.
