Chapter 7.9, Problem 1P
A set of measurable parameters with values specific to the product that together define the product is called the specifications. These parameters are either physical properties of the product or the capabilities of the product. Log on to the Internet to extract the specifications of a product and to identify these two classes of specifications.
Expert Solution & Answer
To determine
The specifications of a product and to identify the two classes of specifications
Explanation of Solution
Product Specification is a document which provides critical defining information about a product and it includes the identification of the manufacturer. The designer of the product should take care that the product meets its specifications. Product specification contains a product identification and detailed description of the product.
Physical properties of the product includes the study of matter
Example-absorption, area, brittleness of material, etc.
Product capability is the output of the product which is needed by the customer.
The two classes of specification are as follows.
1. Prescriptive specification-This type of specification deals with the clauses for the methods of construction. Most of the projects are a part of prescriptive specification.
2. Performance specification -This type of specification deals with the product performance and for how long the product is good to go. It covers all the performance characteristics of the product.
Product specification sheet is as follows.
Product-PU001MONO

The following tools / resources can be useda. Chatgptb. Matlab You may use your own engineering judgement to make any assumptions on any “missing” details of your scenario, provided that you state your assumption(s) and provide your justification(s).
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 Ti-6Al-4V…
