Job Safety Analysis on a task and must have a minimum of five discrete steps and some risks associated with performing it. This task couldbe  changing the tire on your car.

The following is a series of questions pertaining to the NSPE Code of Ethics. Please indicate whether the statements are true or false. These questions are provided by the NSPE. Note: This ethics test is intended solely to test individual knowledge of the specific language contained in the NSPE Code of Ethics and is not intended to measure individual knowledge of engineering ethics or the ethics of individual engineers or engineering students. Engineers may issue subjective and partial statements if such statements are in writing and consistent with the best interests of their employer, client or the public.

Question 2 In a test measuring the life span of a certain brand of tire, 100 tires are tested. The results showed an average lifetime of 50,000 miles, with a standard deviation of 5,000 miles. One hundred thousand of these tires have been sold and are on the road. (a) After what mileage would you expect 10% of the tires to have worn out? (b) How many tires are expected to wear out between 60,000 and 70,000 miles? (c) How many tires are expected to have a life of less than 20,000 miles? (d) What are your major assumptions in the calculations for (a), (b) and (c)? (e) Estimate the 95% confidence interval on the population mean.

Case Study – The New Engineer   Jeff was just hired by GSI, Inc. to be their Environmental and Safety Coordinator.  This is Jeff's first position after completing his engineering degree.  He had taken a course in safety engineering as part of his studies and felt confident that he could handle the job.   Management at GSI, Inc. has assured him that they are committed to maintaining a safe workplace.  They have never had an individual dedicated to this task full-time.  They will implement his recommendations if he can justify them.   As Jeff begins to get familiar with the operations, he spends considerable time on the production floor.  He notices workers clean their tools before break with a liquid from an unmarked 55-gallon drum.  They also use this liquid to clean residue from their skin.  They use paper towels to dry their tools and hands, throw these towels in the trash, and head to the break room for a snack and/or smoke.   In talking with the workers, Jeff learns of some of…

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…

Q3: Monitoring and measuring (audits)  (a) Based on the scenario only, comment on the approach taken to the audit.  (b) Advise the MD on the differences between an audit and a workplace inspection.

The possibility for Occidental mechanical damage in the automotive shop isA nonexistent B rare  c always present d none of the answers listed Foam fender covers are usually about how thick 0.0625 0.125. 0.25 0.375. The best way to minimize, accidental mechanical damage is two Think carefully about the task or work you're performing Replace as many components as possible Follow you experience when  repairing a vehicle

The design process Identify the problem Do research Develop possible solutions Choose one solution Design and construct a prototype.  Test the prototype Communicate results Evaluate and redesign. 8. How would an engineer use the design process to build a car that uses less gas?

Please answer the 4th question

Select whether the following statement's are true or false: Structural safety is solely the responsibility of the aircraft manufacturer and the airworthiness authorities. If a structural component is not inspectable, it can still be certified according to one of the available design philosophies. Decreasing the stress amplitude while maintaining the mean stress means that less work or energy is applied to the structure, and thus less damage is caused resulting in a longer fatigue life.

An accident investigation report must include all of the following except: The date of the accident Names of those witnessing the accident A description of the incident Factors that contributed to the incident
