Learning Goal: To use the principle of superposition to relate external axial loads on a bar to axial deflections. Under certain conditions, the effect of complicated loads can be calculated by combining the effects of simple component loads. This is called the principle of superposition. This method can only be used when the internal axial force N in a body is linearly related to the displacement or external loading, and the deflections are small enough that the body's geometry does not change significantly. If a complicated load can be expressed as a linear combination of the simpler loads, then the stress or displacement at a point will be the same linear combination of the corresponding responses in the simpler loads. Figure B A 1 of 2 1 KN deflection at point A is deflection at point A is flexibility factor.) Part A Larger load A horizontal bar is attached to a wall. When a force of 1 kN is applied at point A (Figure 1), the AA = 0.47 mm. When a 1 kN force is applied at point B…
For the simply supported beam subjected to the loading shown, derive equations for the shear force V and the bending moment M for any location in the beam. (Place the origin at point A.) Let a=4.50 m, b=5.00 m, c= 2.75 m, P = 33kN and M = 195kN-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. 1.Calculate the reaction forces Ay and Cy acting on the beam. Positive values for the reactions are indicated by the directions of the red arrows shown on the free-body diagram below. (Note: Since Ax = 0, it has been omitted from the free-body diagram.) (in kN) 2.Determine the shear force acting at each of the following locations: (in kN)(a) x = 4.50- (i.e., just to the left of point B)(b) x = 4.50+ (i.e., just to the right of point B)(c) x = 9.50- (i.e., just to the left of point C)(d) x = 9.50+ (i.e., just to the right of point C)Note that x = 0 at support A. 3.
