PROBLEM SET 4
1. Draw the shear and bending moment diagrams for the beam and loadings shown. Indicate thevalues at all change of loading positions and at all points of zero shear. Also indicate the
degree of each curve and determine the absolute maximum values of the shear and bending
moment. Use the METHOD OF SECTIONS.
(ANSWER: Vmax= 30.5781 kN , Mmax= 112.8374 kNm)
(ANSWER: Vmax= 30.5781 kN , Mmax= 112.8374 kNm)
2. Use the Method of Sections to draw the shear and bending moment diagram of beamABCDEF. Indicate the degree of each curve. Identify the value of absolute maximum shear
and bending moment. Note that Cis an internal pin andFis a roller support.
(ANSWER: kNV 30max = Mmax = 109.7321 kNm)
