![]() Positive and negative internal shearing forces Is shown above the corresponding shear force diagram for that beam. The free body diagram of a horizontal beam. If you don't wind up back at zero, go back and check your previous work. You can ignore any moments or horizontal forces applied to the body.īy the time you get to the right end of the plot, you should always wind up coming back to zero.For non-uniform distributed forces, the shape of the shear diagram plot will be the integral of the force function.For any uniform distributed forces you will have a linear slope where the magnitude of the distributed force is the slope of the line (positive slopes for upwards distributed forces, negative slopes for downwards distributed forces). ![]()
