Question details

Part 1 Use the graphical methad to construct the shear foce and bending ma ment diagrams for tne beam shown. Leta = 3.5 m b = 2.0 m, c = 2.5 m, d = 4.0 m, wAD-70kN/m wDE= 50kN/m PB = 120kN, and MA-50kN-m. Construct the shear- force and bending-moment diagrams on paper and use the results to answer the questions in the subsequent parts of this GO exercise. frictionless pin WDE MA it has been omitted from the free- С late he eaction forces Ay C body diagram.) and Ey acting on the beam. Positive values for the eactions are indicated by the directions of the red arrows s own on the ree-body diagram below. Note: Since A Pa frictionless pin WDE м, 1 KN Cy-L Answer * 1: tne number of significant digits is set to 4, the tolerance is +/-290 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%*Part 2 Determine the shear force acting at each of the following locations (a)x 0+ m (i.e., just to the right of support A) (b) x - 3.5- m (i.e., just to the left of point B) (c) x-3.5+ m (i.e., just to the right of point B) (d) x = 5.5-m (i.e., just to the left of point C) (e) x-5.5+ m (i.e., just to the right of point C) (f) x = 12.0-m (ie, just to the left of support E) When entering your answers, use the shear-force sign convention detailed in Section 7.2 Answers: (a) V- (b) V- (c) V (d) V (e) V (f) V- *1 kN 2 kN *3 kN *4 kN *5 kN 6kN 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% Answer *6: the number of significant digits is set to 4; the tolerance is +/-2% *Part 3 The shear-force diagram crosses the V = 0 axis between points A and B. Determine the location XAB (measured from A) where V = 0 kN Answer: XAB *i m The number of significant digits is set to 4; the tolerance is +/-2%*Part 4 The shear-force diagram also crosses the V = 0 axis between points D and E.
