A bent pipe is attached to a wall with brackets as shown. A
force of F = 180 lb is applied to the end of the tube with
direction indicated by the dimensions in the figure.
Determine the support reactions at the brackets B, C, and
D. Model these brackets as journal bearings (only force
reactions perpendicular to the axis of the tube) and neglect
couple moment reactions. Assume the distance between the
supports at B and C and the tube bends nearby are
negligible such that the support at C is directly above the
support at D and the dimension g gives the distance between
supports B and C. Enter your answers in Cartesian
components.
