Q7. A company is interested in verifying correctness of an automated assembly operation that involves parts that fit within the 75 mm cube and use six small metal screws with 2 mm diameter head and 8 mm height. A major concern for this operation is reliability of screw driving operation. Failure of screw driving can lead to either missing screws or partially inserted screws. Select the most cost-effective equipment for performing this inspection step to ensure that defective assemblies can be detected. There is no unique correct answer for this problem. Full credit will be given for any reasonable solution.

Determine the strength coefficient and strain hardening exponent from the data given in the table below. Refer to the derivation of equations and graphs where needed. Characterize the material by evaluating its strength coefficient and strain hardening exponent using cyclic data received from the testing laboratory. The true stresses and true strains are considered. The constants for the data are determined as follows: For metal, a power law exists between the true stress and true inelastic strain: σ = Kε^n (1) Taking the natural log of both sides, obtain: ln(σ) = n ln(ε) + ln(K) (2) Conversion from true stress to engineering stress: σ_e = σ(1 + ε) (3) Obtaining inelastic strain: ε_in = ε - ε_a (4) Conversion from true strain to engineering strain: ε_e = nε_in + ln(K) (5) Point j E (in./in.) ε_a (ksi) E_a true _plastic ln(ε_a) ln(_plastic) (in./in.)
