10c The 9.75 m long beam is simply supported at A and B shown below with a uniformly distributed load (UDL) between A and C of 4.75 kN/m and a concentrated point load of 12.50 kN at point D (i.e., midpoint between C & B). Determine the shear force in kilonewtons (kN) at the midpoint of AB (i.e., mid-beam). Assume the beam is weightless and give your answer in kilonewtons (kN) to 2 decimal places. 12.50 kN 4.75 kN/m 1.125 m D A 7.50 m 2.25 m В Answer:

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

Draw the free body diagram, shear force diagram, and bending moment diagram for the beam shown below and calculate values at each point:

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.

41. The wide-flange I beam as shown is 20 ft. long. It is fixed at one end and free at the other. A twisting moment of 30,000 lb-in. is applied at the free end. If E=30×10° psi and G =12x10° psi, compute the maximum normal and shearing stresses due to bending and the maximum shearing stress due to twist. What is the angle of twist of the beam at the free end? 10.5" 1.368" 0.845" 10" prob 41

I have gotten this question wrong twice, so the answer isn't 3.43 or .413 kN/m.
