- A large number of uniform and identical cantilever beams, each 1 m long and 146 N / m in weight, are used to support pipes. Consider that the length of the tubes acting under a typical ABCD beam is 1.2 m. And that tubes B and C, plus their contents, weigh 365 N / m and 510 N / m, respectively, determine the reactions at the end set in A, of the cantilever beams.arrow_forwardNo. 2arrow_forwardNo. 3arrow_forward
