What is the major drawback of the Merit index?
Select one:
O a. The merit index can consider only one criterion at a time
O b. It is useful only for forming a subjective value of a material
O c. The algebra is too hard to be performed successfully
O d. There are no drawbacks to the Merit index

Set up a spreadsheet solution to this problem. This will require that you derive one
formula to express the relationship between the friction coefficient, the spring constant,
and the spring compression; and a second formula to find the cost of using different slide
and spring types. Set up your spreadsheet as shown below. You can fill in the
"Acceptable?" column manually, rather than using a formula. Turn in a copy of your

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…

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.

Kindly do not re-submit your answers if you have solved the problems in this post. I post multiple questions of the same type to get an idea from other tutors. Thank you, Tutor! S.2
Statics of Rigid Bodies
Content Covered:
- Method of Sections
Direction: Create 1 problem based on the topic "Method of Sections" and then solve them with a complete solution. In return, I will give you a good rating. Thank you so much!
Note: Please bear in mind to create 1 problem based on the topic "Method of Sections." Be careful with the calculations in the problem. Kindly double check the solution and answer if there is a deficiency. And also, box the final answer. Thank you so much!

Topics:
Statics of Rigid Bodies, Equilibrium of Rigid Bodies, Equilibrium in Two Dimensions, etc.
I will rate you with “LIKE/UPVOTE," if it is COMPLETE STEP-BY-STEP SOLUTION.
If it is INCOMPLETE SOLUTION and there are SHORTCUTS OF SOLUTION, I will rate you with “DISLIKE/DOWNVOTE.”
THANK YOU FOR YOUR HELP.
PS: If you have answered this already, don’t answer it again; give chance to other experts to answer it. I want to verify if all of you will arrive in the same final answer; thats why I ask it multiple times. If you answer it again, i'll dislike all your entries/answers.
