The diving board consists of a very strong wall with a support pipe embedded into it with very strong concrete. The pipe is welded together with a diving board that has a hollow, rectangular cross section. BOTH THE PIPE AND THE BOARD ARE FABRICATED FROM AISI 1020 HR CARBON STEEL. The arrows in the views on the right represent the forces from each of the animal’s feet as she stands at the end of the board, ready to dive in. EACH OF THESE FORCES HAS A MAGNITUDE OF 1.000 kip.
Problem 1) Look at each of these points and think about the stresses that are generated at that point. Then, for each of
the points a-h write down the stress types that you believe are generated. Select the stress types from this list:
normal stress due to bending
normal stress due to axial loading
normal circumferential stress
shear stress due to direct shear
shear stress due to torsion
normal circumferential stress
shear stress due to bending
Point E Topmost point of the pipe cross section, above the pipe axis, at the point where the pipe meets the wall. Point H: Rightmost point of the pipe cross section, on the neutral surface, at the point where the pipe meets the wall. Point E: Topmost point of the pipe cross section, above the pipe axis, 15 in. from the front of the wall Point F Rightmost point of the pipe cross section, Point C: Top surface of board, on the on the neutral surface, 15 in. from the front of the wall board centerline, 3 in to the right of Point A Top surface of board, on the the pipe center axis board centerline, 14 in from the end of the board. Point B: Front surface of board, on the Point D: Top surface of board, on the neutral plane, 14 in from the end of board centerline, 3 in to the right of the board. the pipe center axis.Solution
Point A-normal stress due to bending.
Poinr B- shear stress due to direct shear
Point C- normal stress due to bending.
Point D- normal stress due to direct shear
Point E- shear stress due to bending.
