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.

This assignment challenges you to reflect critically on Moses’ legacy and draw connections to contemporary urban planning challenges. Reflect on Power and Authority in Planning: How did Robert Moses’ accumulation and use of unelected power shape the urban landscape of New York? What lessons can modern planners learn about checks and balances in urban development?
