Exercise 10. The uniform, horizontal beam shown in Figure 10 is hinged to the ground at A and
supported by a frictionless roller at D. The distance between A and B is /= 4 m and the distance
between A and D is d = 3 m. A force that makes an angle B = 60° with the horizontal is applied
at B. The magnitude of the applied force is P = 1000 N. The total weight of the beam is W = 400
N.
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 A and D.
