(A/B). A beam 7 m long is simply supported at its ends and loaded as follows: 120 kN at 1 m from one end A,
20kN at 4 m from A and 60 kN at 5 m from A. Calculate the position and magnitude of the maximum deflection. The
second moment of area of the beam section is 400 x 10-m* and E for the beam material is 210 GN/m².
1. The cantilever beam in Figure 1 is fixed at A, and is loaded with a distributed load from A
to B and a concentrated moment at C.
Use the GRAPHICAL METHOD to plot the shear force and bending moment diagrams for the
entire length of the beam. Label values at all key locations on the plots (at changes in loads,
maxima, minima, and zeroes).
Annotate your diagrams to explain how they were drawn (e.g. "AQAB = (-12 kN/m)(1 m) =
-12 kN" and "(dQ/dx)AB = -12 kN/m").
