Problem 4.3 The uniform, horizontal beam shown in Fig. 4.50 is hinged to the ground at point A and supported by a friction- less roller at point D. The distance between points A and B is 1 = 4 m and the distance between points A and D is d= 3 m. A force that makes an angle B= 60° with the horizontal is applied at point B. The magnitude of the applied force is P = 1000 N. The total weight of the beam is W = 400 N. %3D %3D %3D %3D By noting that three-quarters of the beam is on the left of the roller support and one-quarter is on the right, calculate the x and y components of reaction forces on the beam at points A and D. Answers: Rp = 1421 N (↑) RAx = 500N (-) RAV = 155N ()
