A materials engineer wants to understand the relationship between the strength of plastic cases and the temperature at which the strength measurements were made. The engineer collects several samples from the manufacturer and records the following observations. Using the data below and what you have learned in Forecasting, determine the following (use four decimal places for values): 1) Which is the explanatory variable? 2) If we want strength to increase, what must we do to the temperature? Increase OR Decrease? 3) What should be the value of Temperature if we want Strength at 5,000? 4) What is the value of the standard error? Sample Temperature 1 185 2 183 3 187 Strength 5150 5125 5123

The behavior of materials that deform when loaded but return to their original shape after the load is removed. The linear relationship between stress and strain in the elastic region below the proportional limit. The phenomenon where cracks propagate under loads less than the yield stress due to cyclic loading. The material property determined using the Charpy or Izod test. The point at which the stress vs strain becomes non-linear in an elastic material,

Question 2 You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the…
I tried 33.7oC and also 50.517oC but it still says it is incorrect (view attached screenshot). I appreciate your efforts, but unfortunately it says it is still wrong. Any more ideas of what the correct answer might be? I really want to understand how to solve this problem correctly. Thank you!

A new electronic component for aircraft is tested to withstand temperatures as low as -50°F. One engineer suggests that the device cannot actually stand temperatures that low. What are the Type I and Type II errors? Type I: The device CAN NOT withstand temperatures as low as -50F but the engineer incorrectly finds that it CAN.Type II: The device CAN withstand temperatures as low as -50F but the engineer incorrectly finds that it CAN NOT. Type I: The device CAN withstand temperatures as low as -50F but the engineer incorrectly finds that it CAN NOT.Type II: The device CAN NOT withstand temperatures as low as -50F but the engineer incorrectly finds that it CAN. Is the answer the first or second bullet point?

Part 1: Suppose that our company performs DNA analysis for a law enforcement agency. We currently have 1 machine that are essential to performing the analysis. When an analysis is performed, the machine is in use for half of the day. Thus, each machine of this type can perform at most two DNA analyses per day. Based on past experience, the distribution of analyses needing to be performed on any given day are as follows: (Fill in the table) Part2: We are considering purchasing a second machine. For each analysis that the machine is in use, we profit 1400$. What is the YEARLY expected value of this new machine ( ASSUME 365 days per year - no weekends or holidays
