The analysis of a proposed design for a component revealed a state of tensile stress with a mean value of 25,000 psi and a standard deviation of 5,000 psi. Characterization of the component's material indicated that the mean value of the strength is 60,000 psi. The engineer wishes to know the maximum value of the standard deviation for the strength that will ensure that the component reliability does not drop below 0.999. Determine the permissible safety margin (SM) and the standard deviation of strength. (round SM to 2 decimal places, e.g. XXX.Xx and os to the nearest psi integer) SM

25000 bolts are going to be used to fix a certain structure. The bolts have a mean fatigue life of 10000 days with a standard deviation of 2000 days under heavy dynamic loading conditions.What is the probability that a bolt will fail between 8250 and 12500 days of use?
ASTM Standard E23 defines standard test methods for notched bar impact testing of metallic materials. The Charpy V-notch (CVN) technique measures impact energy and is often used to determine whether or not a material experiences a ductile-to-brittle transition with decreasing temperature. Ten measurements of impact energy (J) on specimens of A238 steel cut at 60ºC are as follows: 64.1, 64.7, 64.5, 64.6, 64.5, 64.3, 64.6, 64.8, 64.2, and 64.3. Assume that impact energy is normally distributed with σ = 1J. Find a 95% Confidence interval for μ, the mean impact energy.
Experiments were conducted in a tension testing machine to evaluate the material properties of two metallic rods both having diameter equal to 10 mm. First rod having modulus of rigidity of the material equal to 400 tonnes/cm2 when subjected to an axial tensile force of 6 kN, the change in its diameter was observed to be 0.0018 cm. The value for the bulk modulus of the second metallic rod is same as that of the first one but modulus of elasticity 18% more. Based on the material properties calculate and compare the values of different moduli as well as Poisson’s ratio for both metallic rods. Justify your answer with reasons.
