Loading: The kid is trying to spin the rod which is stock at the ground and free on top. She has weight of 120 lbs. She is creating a twisting moment of 400 lb.in around the vertical pipe. Section properties: The vertical pipe has an outer radius of 1.8 inches and an inner radius of 0.5 inches. The length of vertical pipe is 100 inches. | Material properties: The pipe material is steel which has modulus of elasticity (E=20000 ksi) and Shearing modulus of (G=1100 ksi). It has ultimate normal strength of 60 ksi and ultimate shearing strength of 40 ksi. a) Name all types of stress(es) exist in the vertical pipe b) Calculate amount of stress(es) that you recognized previously c) Name types of strain(s) or deformation(s) in the pipe. d) Calculate amount of strain(s) or deformation(s) you recognized. Loading: The expected loading for a kid hanging from the bar is 180 lbs. Material: The same material is used in all parts. The ultimate normal strength is 380 psi and the ultimate shearing strength of 270 psi. Factor of Safety: Use factor of safety of 1.4 in your design: e) Predict the load in each chain and calculate the required size of chain used in each handle. Accompany a simple drawing to show the chain detail. f) Determine the diameter of the pin that is used to connect each handle to the bar.
