1.10.4 [5] <$1.5> Assume a fabrication process improves the yield from 0.92 to 0.95. Find the defects per area unit for each version of the technology given a die area of 200 mm?.

No wrong answer please , i could downvote The piece of suture is tested for its stress relaxation properties after cutting 3 cm long sample with a diameter of 1mm. The initial force recorded after stretching 0.1 cm between grips was 5 Newtons. Assume the suture material behave as if it has one relaxation time. The gage length was 1 cm. a. Calculate the initial stress. b. Calculate the initial strain. c. Calculate the modulus of elasticity of the suture if the initial stretching can be considered as linear and elastic. d. Calculate the relaxation time if the force recorded after 10 hours is 4 Newtons.

Detailed steps

1. What are the elastic modulus (E) and the Poisson's ratio () used to indicate? 2. Illustrate the differences between actual stress and engineered stress with strain, and also describe their underlying physical concepts. 3. If the engineering strain is 2% for a specific state of uniaxial stress, what is the real strain?   Please solve for all in full detail and step by step

In your summer internship, you are tasked with measuring the ultimate tensile strength of a material to determine if it meets your company’s (Superior Super Ships Inc) specification. Your boss is worried that the new low-cost supplier, Shoddy Alloys Inc, may not be reliable but it is the only way to source on-time the SS304 needed to make finishings for Jeff Bezos’ new yacht, the Black Pearl. You collect several load versus displacement curves, as illustrated below. The initial diameter of the round gauge section is 0.25 in. You also collect the instantaneous diameter of the specimen during the test using a laser. Using the provided data, calculate what is the ultimate tensile strength measured in this test?

A plate with a center hole is subjected to both of axial force (F) and bending moment (M; acting about weak axis). Predict the fatigue failure with 50% reliability. The plate is machined from alloy steel (S.= 470 MPa and Sy= 350 MPa). M M [Top View] M M [Side View] Where, w=35mm, d=4mm, h=2mm. 1) Calculate fatigue strength (S,). 2) Calculate o. and o. for two loading cases: (a) F=Fosin (wt-10) and M=0 F=Fosin (t+10) +k and M=Mo and (b) Note: F.= k = 2 kN and M.= 4 Nm 3) Determine if the bar is safe against fatigue failure and calculate safety factor for the cyclic loading cases; assume (a) Obm = 0 MPa and O = 80 MPa and (b) oim = 85 MPa and OE = 70 MPa regardless of the answers in question 2).
