![]() However, if a beam has more than two reaction loads, as in the case of a beam fixed at one end and either pinned or fixed at the other end, it is statically indeterminate and beam deflection equations must be applied in addition to the equations of statics to determine the reaction loads. If a beam has two reaction loads supplied by the supports, as in the case of a cantilever beam or a beam simply supported at two points, the reaction loads may be found by the equilibrium equations and the beam is statically determinate. These consist of a summation of forces in the vertical direction and a summation of moments. A right Riemann sum with 10 subintervals for the function f ( x) sin ( 2 x) x 2 10 + 3 on the interval. Two equations of equilibrium may be applied to find the reaction loads applied to such a beam by the supports. Consider this applet 1, in which you will initially see the situation shown in Figure 4.3.2. ![]() IED Activity 3.4 Linear Dimensions 1. In the space provided below each drawing, next to the appropriate letter, give the reason for each correction and cite the dimensioning guideline that is misapplied. 1.3.4 Introduction to Reaction Forces and Moments on Beams Under Transverse Loadingįigure 1-30 shows a beam under transverse loading. Circle each error and place a letter, A through P, next to each error on the drawing.
