An element in plane stress is subjected to stresses Ox, Oy, and Txy (see figure). The material is aluminum with modulus of elasticity E:= 10 (10%) psi and Poisson's ratio v:=0.25. Hint: start with Hooke's Law for Plane Stress (Eq. 7-35 and 36) and the relationship between G and E! (a) Determine the strains for an element oriented at an angle e. (b) Determine the principal strains. (c) Determine the maximum shear strains. 0x := 3000 psi , := 600...

Question 15 (1 point) A material element is subjected to plane stress conditions. The stresses at the point of interest are as follows (units of MPa are assumed): 0x =-87 Oy =36 Txy =-77 Determine the normal strain in the z-direction, Ex, in microstrain (to one decimal place). So if the value is 18.4 E-06, just enter "18.4". You may assume Young's modulus is 72 GPa and Poisson's ratio is 0.3 for this material.

2. A 1-D mechanical bar (see Figure) consisting of two materials is clamped at x-0 while subjected to a displacement (u 10 microns) at x-2mm as shown in the figure. The materials are isotropic and perfectly bonded together. The Youngs modulus for the two materials is E1 -10 GPa and E-50GPa respectively. For the mechanical bar below assume a simple 1D problem and answer the following questions What are the stresses (o) strains (Ex) and displacements (u) in each of...

We were unable to transcribe this imager Engineenng eratures in the rim by around 313 K compared with earlier piston designs. The piston's steel skirt is much more rigid than the aluminum skirt in smaller deformation and allowing for designs with tighter clearances tin harmful exhaust emissions) from the piston. This design has been shown to reduce piston termn results in a more stable piston with less oil consumption (thus further r which are machined prior to welding. The process...
