The figure shows the stress-strain curve for a material. The scale of the stress axis is set by s = 330, in units of 106 N/m^2. What are (a) the Young's modulus and (b) the approximate yield strength for this material? (a) Number Units (b) Number Units
An elastoplastic material with strain hardening has an elasto-plastic stressstrain relation. The modulus of elasticity (E) is 25x106 psi, yield strength is 70 ksi, and the slope of the strain hardening portion of stress-strain diagram is 3x106 psi Problem # 4 Calculate: A) the strain that corresponds to a stress of 80 ksi B) If the 80-ksi stress is removed, calculate the permanent strain
Identify the material. that fits the stress-strain curve. A) MILD STEEL Yield Strength: 30 kN, Ultimate Strength: 40 kN, Young Modulus: 30/0.7 kN/mm = 43 kN/mm B) ALUMINUM Yield Strength: 20 kN, Ultimate Strength: 26 kN, Young Modulus: 20 kN/mm C) CAST IRON Yield Strength: N/A, Ultimate Strength: 20 kN, Young Modulus: 20/0.4 kN/mm = 50 kN/mm D) COPPER Yield Strength: 30 kN, Ultimate Strength: 35 kN, Young Modulus: 30 kN/mm Instructions CLI Tesile TesTeR Test Specimens Material - Mild...
The cantilevered bar in the figure is made from a ductile material and is statically loaded with Fx-320 lbf, Fy = 255 lbf, and F- 105 lbf. The critical stress element experiences = 58.4 kpsi, σ x ,axial =0.407 kpsi and τ = 15.6 kpsi. Determine the minimum factor of safety for fatigue at point A, based on infinite life. If the life is not infinite, estimate the number of cycles. The force F is applied as a repeated load...
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...
