Question details

*Chapter 7, Supplemental Question 039 Multistep Part 1 For the simply supported beam subjected to the loading cho n, derive equations for the shear force vand the bending moment M for any lccation in the beam Place the origin at point A. Let a-2 000 m, b=6.50 m, Ps = 20kN 욘nd PC = 50kN. Construct the shear-force and bending-moment diagrams on paper and use the results to answer te questions in e subseq Jent parts of this GO exercise 尼 Calculate the reaction orces and Dr acting on the beam. Positive values forte reactions are inc ca e b che directions o the red arrows n on the tree-body diagram below. Note: Since O it has been omitted rom the re -body D, Answers Answer 1: the number of significant oigits is set to 4; the tolerance is +-2% Answer * 2: the number of significant digits治set to 4, the tolerance is +/-2%*Part 2 Determine the shear force acting at each of the following locations: (a) x 1 m (b) x = 4 m (c) x = 9.500 m Note that x0 at point A. When entering your answers, use the shear-force sign convention detailed in Section 7.2. Answers: (a) V (b) V- (c) V 82 kN 33 kR Answer * 1: the number of significant digits is set to 4; the tolerance is +/-2% Answer *2: the number of significant digits is set to 4; the tolerance is +/-290 Answer * 3: the number of significant digits is set to 4; the tolerance is +/-290*Part 3 Determine the bending moment acting at each of the following locations: (a)x-1 m (b) x-2.000 m (i.e., at support B) (c) x - 4 m (d) x-8.500 m (i.e., at point C) (e) x9.500 m Note that x = 0 at point A. When entering your answers, use the bending-moment sign convention detailed in Section 7.2. Answer:s (b) M- (c) M- (d) M- (e) M *1 kN-m *2 kN-mm *3 kN-m *4 kN-m *5 kN-m Answer * 1: the number of significant digits is set to 4; the tolerance is +/-2% Answer *2: the number of significant digits is set to 4; the tolerance is +/-2% Answer *3: the number of significant digits is set to 4; the tolerance is +/-2% Answer *4: the number of significant digits is set to 4; the tolerance is +/-2% Answer *5: the number of significant digits is set to 4; the tolerance is +/-2%Part 4 Use your bending-moment diagram to determine the maximum positive bencing moment,max, h maximum negative bending moment, Mmax, n and their respective locations, Xmax, pos and max, neg: Use the bending-moment sign convention detailed in Section 7.2 The maximum negative bending mcment is the negative moment ith the largest absolute value. Enter the max mum negative bending moment as負negative value ter the Answers: 1 kN·m, x = - kN-m, xmas, nag- max, pas 1 m Answer * 1: the number of significant digits is set to 4; the tolerance is +/-2% Answer * 2: the number of significant digits is set to 4, the tolerance is t/-2% Answer *3: the number of significant digits is set to 4; the tolerance is 1/-2% Answer *4: the number of significant digits is set to 4: the tolerance is +/-2%
