The cantilevered bar in the figure is made from a ductile material and is statically loaded with F,, = 200 lbf and Fx = F₂ = 0. Analyze the stress situation in rod AB by obtaining the following information. Note that the stress concentration factors are neglected in the following questions (Kt and Kts=1). (a) Determine the precise location of the critical stress element. (b) Sketch the critical stress element and determine magnitudes and direction for all stresses acting on it. (Transverse shear may only be neglected if you can justify this decision.) (c) For the critical stress element, determine the principal stresses and maximum shear stress. 6 in 1-in dia.

A laminated thick-walled hydraulic cylinder was fabricated by shrink-fitting jacket having an outside diameter of 300mm onto a SS 304 steel tube having an inside diameter of 100mm and an outside diameter of 200mm as shown in the figure. The interference (8) was 0.15mm. When the Young's modulus for both SS304 and 1020 steel is the same as 200GPa, and the Poisson's ratio is also the same as 0.3 for both materials, find the followings. Initially 100 mm Initially 200 mm Initially 300 mm SS 304 1020 steel (a) P; (interfacial contact stress) (b) The maximum stresses (σ, and σ+) in the laminated steel cylinder resulting from the shrink fit.
