Question
I will be selling a Summer Camp Innovative Sleeping System
(SCISS) that suspends beds from the ceiling to make cleaning
the floor easier (and to avoid snakes, bugs, and rodents).
The top post is a 4-foot long steel post with a
2.5 inch x 2.5 inch cross section.
The bottom post is a 3-foot long aluminum post with a
2 inch x 2 inch cross section.
(a) What is the displacement of point “C" for the loading
shown?
(b) Has the yield stress of either post been exceeded?
(c) What is the displacement of point “C” if the 120 lb loads
are put on the top beds, and the 180 lb loads are put on
the bottom beds?
(d) For the loading in part (c), has the yield stress of either
post been exceeded?
