Chapter 4, Problem 117P

hi can you please help me in finding the stress intensity factor using a k-calcluator for the scenario attathced in the images.

Hi, can you please help me .Identify and justify suitable analytical techniques of the scenario below, bearing in mind the kinds of information being handled to reach a conclusion (methodology). A child swing set was discovered to have failed at the fixing at the top of the chains connecting the seat to the top of the swing set. A 12 mm threaded steel bolt, connecting the shackle to the top beam, failed at the start of the threaded region on the linkage closest to the outside side of the swing set . The linkage and bolts were made of electro galvanised mild steel . The rigid bar chain alternatives and fixings were of the same material and appeared to be fitted in accordance with guidelines. The yield strength of the steel used is 260 MPa and the UTS is 380 MPa. The bolt that failed was threaded using a standard thread with a pitch (distance between threads) of 1.75 mm and a depth of approximately 1.1 mm. The swing set in question had been assigned to ‘toddlers’ with the application of…

Hi, can you please define and calculate the failure mode of the linkage that failed on the swing (images added) : A child swing set was discovered to have failed at the fixing at the top of the chains connecting the seat to the top of the swing set. A 12 mm threaded steel bolt, connecting the shackle to the top beam, failed at the start of the threaded region on the linkage closest to the outside side of the swing set . The linkage and bolts were made of electro galvanised mild steel . The rigid bar chain alternatives and fixings were of the same material and appeared to be fitted in accordance with guidelines. The yield strength of the steel used is 260 MPa and the UTS is 380 MPa. The bolt that failed was threaded using a standard thread with a pitch (distance between threads) of 1.75 mm and a depth of approximately 1.1 mm. The swing set in question had been assigned to ‘toddlers’ with the application of a caged-type seat. However, the location was within the play area not…

11-70. A shear stress (pure shear) of 5000 psi exists on an element. (a) Determine the maximum tensile and compressive stresses caused in the element due to this shear. (b) Sketch the element showing the planes on which the maximum tensile and compressive stresses act.

11-20. An aluminum specimen of circular cross section, 0.50 in. in diameter, ruptured under a tensile load of 12,000 lb. The plane of failure was found to be at 48° with a plane perpendicular to the longitudinal axis of the specimen. (a) Compute the shear stress on the failure plane. (b) Compute the maximum tensile stress. (c) Compute the tensile stress on the failure plane. hp
