Need ASAP, Show all steps. Thanks.
Supplemental Problems 10.16 A 12-in.-diameter structural nickel steel specimen was subjected to a tension test. After rupture it was determined that the 2-in. standard-gage length had stretched to 2.42 in. The minimum diameter at the fracture was measured to be 0.422 in. Compute the percent elongation and percent reduction in area. 10.20 During a tensile test of a steel specimen, the strain at a stress of 35 MPa was calculated to be 0.000 170...

1. (5 pts) If a steel bar subjected to uniaxial tension enters into t the plasticity region of the stress-strain curve, which of the following statement is ALWAYS true? (select all that apply) a. Stress in the bar has exceeded yielding strength: b. Stress in the bar has exceeded proportional limit; c. The total strain can d. The plastic strain can be fully recovered if tensile load is fully released; be fully recovered if tensile load is fully rel released;...

S. Draw a possible stress strain graph for a material with a yield stress of 300 MPa, an elastic modulus of 200 GPa, a UTS of 450 MPa and a ductility of 20%. Calculate the elastic strain at the point where the material starts to plastically deform. 6. A nylon rope with an elastic modulus of 3 GPa is placed under a force of 17.5 kN. The cross-sectional area of...

2. Two circular rods are loaded in tension along their longitudinal axis. Both rods have a diameter of 20 mm and a length of 150 mm. One bar is made of aluminum and the other is hot pressed silicon nitride (SigN). Both have an applied tensile load of 80 kN. Assume that both materials behave elastically under this loading condition (the aluminum does not plastically deform and the silicon...

Single Cell Torsion (and a little buckling) 2. (20 pts) Suppose we wish to design a minimum weight shaft of Im length to support a limit Torque of 35 kN-m. The material is specified as aluminum 6061-T6 with yield strength of 240 MPa, Young's Modulus 70.0 GPa and Poisson Ratio 0.33. We recognize that for this pure torsion application a thin-walled, hollow circular shaft is the optimum configuration, but what radius and wall thickness will minimize the weight? Determine the...

2) One scenario that has been examined in the failure investigation of the Space Shuttle Columbia is the impact of a chunk of polyamide foam of mass of 1.211 kg, of dimensions of 0.508 m wide x 0.406 m long x 0.152 m tall, traveling at 457.3 m/s with a thermal heat-shielding tile, essentially composed of silica (SiO) A) (4 pts.) Calculate the kinetic energy with which the polyamide foam hit the silica...
