question!
(a) You have been asked to select the best material for redesigning a walking stick (Figure Q4 (a)). It is basically a long pole with fixed length, L, and an unknown cross-section, A. In order to give strong support, the pole must store as much elastic energy as possible. It must be able to support under end load without buckling and the cost of material less than $ [in USD]. What is the performance for this design? (10 marks) (b) Derive the performance index for stored energy of the walking stick. The buckling equation, stored energy (in Joule) and cost (in USD $/kg) equation are given; πA²E Fend Buckling 4L² = FAL 4E Stored energy; U = Cost; So=CPLA (15 marks)
