If a machine part is made of tool L2 steel and a critical point in the material is subjected to in-plane principal stresses s1 and s2 = -0.5s1, determine the magnitude of s1 in ksi that will cause yielding according to the maximum shear stress theory.
ME 270 – Lect. 2 – Design Process & DtC Four-Stages of Creative Thinking Process • Design Process 1) Preparation (stage 1): – The elements of the problem are examined and their interrelations • What is a “Product Design Specification” (PDS) are studied. Tradeoffs Boundaries Organize knowledge. 2) Incubation (stage 2): • Concurrent Engineering –“ Sleep on the proble
