A fiberglass bracket ABCD with a solid circular cross section has the shape and dimensions shown in the figure. A vertical load P = 40 N acts at the free end D. (a) Determine the minimum permissible diameter
of the bracket if the allowable bending stress in the material is 30 MPa and b = 37 mm . Note: Disregard the weight of the bracket itself. (b) If d =10 mm , b =37 mm , and
= 30 MPa , what is the maximum value of load P if vertical load P at D is replaced with horizontal loads P at B and D (see fgure part b)？
