3. In Problem 2 beam has a cross-section as shown below. Moment of inertia of the cross section is 450 in4 and the centroid is located 9.9 inches from the bottom of the beam. At x= 8 ft, ● ● Find the bending normal stress Find bending shear stress at welded joint -18.0- 1 Y 1.0 1.0 12.0 To scale Welded joint

Find the Magnitude of the Maximum Shear Stress in the below beam and cross-section, if: W = = 6 kN/m L = 5 m b = 55 mm h = 144 mm Ensure that your answers are in MPa. Mo W Cross-Section: L b h

Draw the shear force and bending moment diagrams for 2 kip the beam under the external loadings shown in the figure. 200 lb/t Note use the graphical method; show all the critical tuming points of each curve, along with the calculation steps used in determining the critical points. 9

10 in 1 in 1 in V 12 in 1 in 5 in The steel wide flange beam shown above is fabricated using three rectangular plates, welded together. Assume the following cross-section properties: A = 27 in3 • Y = 8.204 in (distance from bottom of shape to neutral axis) • | = 739.88 in (moment of inertia about neutral axis) The beam is subjected to a shear force V = 20 kips. Which of the following is closest to the shear flow carrled by the weld attaching the top flange (10" x 1" top piece) to the rest of the cross-section?

PLS ANSWER ASAP, WILL UPVOTE FOR SURE

Please help. Written on paper not typed on computer please. Need help on all questions. Please include all units, steps to the problem and information such as its direction or if it is in compression or tension. Thx.
