WHAT IS ENGINEERING ETHICS
Engineering Ethics is the study of moral issues and decisions confronting individuals and organizations engaged in engineering.
The Study of related questions about moral ideals,character,policies and relationship of people and corporations involved in technological activity.
WHY STUDY ENGINEERING ETHICS
What is the point in studying engineering ethics?
What can be gained from taking a course in ethics?
Engineering ethics course is not about preaching virtue
rather, its objective is to increase your ability as engineers to responsibly confront moral issues raised by technological activity.

CASE 1 : THE CASE OF THE KILLER ROBOT
Jane McMurdock, prosecuttting attorney for the city of Silicon Valley, announced today the indictment of Randey Samuels on charges of manslaughter. Samuels employed as a programmer at the Silicon Techtronic’s Inc. The charge involves the death of Bart Matthews, who was killed last May by an assembly –line robot. Matthews worked as robot operator at Cybernetics Inc.,in Silicon Heights. He was crushed to death when the robot he was operating malfunctioned and started to wave its hands violently.
The Robot arm struck Matthews, throwing him against a wall and crushing his skull. Matthews died almost instantly. According to the indictment, Samuels wrote the particular piece of computer program responsible for the robot malfunction. “There’s a smoking gun!” McMurdock announced triumphantly at a press conference held in the hall of Justice.” We have the hand written formula ,provided by the project physicist, which Samuels was supposed to program. But he negligently misinterpreted the formula leading to this huge gruesome death. Society must protect itself against programmers who make careless mistakes. The Sentinel – observer has obtained a copy of the handwritten formula in question. There are actually three similar formulas ,scrawled on piece of yellow legal pad paper.
Each formula describes the motion of the robot in one direction: east-west, North-south and up –down. The Sentinel-Observer showed the formulas to Bill Park a professor of physics at Silicon Valley University. He confirmed that these equations could be used to describe the motion of a robot arm. The Sentinel – Observer then showed Park the program code written by the accused in the programming language. We asked Park who is fluent in C and several other languages, whether the program code was correct for the given robot – arm formulas.
Parks response was immediate. He exclaimed, “By Jove! It looks like he misinterpreted the formula. He’s guilty as hell, if you ask me”. The Sentinel – Observer was unable to contact Samuels for comment. “He is deeply depressed about all this,” his girl friend told us over the phone,” but Randy believes he will be acquitted when he gets a chance to tell his side of the story.

CASE 2: DC – 10 JUMBO JET
The fuselage of the DC – 10 Jumbo jet of which the cargo door is a part was developed by Convair, a sub contractor for McDonnell Douglas. Convair’s senior engineer directing the project, Dan Applegate had written to the Vice president of the company: “The Cargo door could burst open, leading to crash of the plane. Hence the door has to be redesigned and the cabin floor has to strengthened”.
Top Management at Convair neither disputed the technical facts or the predictions made by Applegate. The liabilities and the cost of redesign were to high. Two years went by. In 1974 the cargo door of DC – 10 Jumbo burst open and the jet crashed near Paris killing 346 . Issues:
CASE 3: WHISTLE BLOWING
Definition: Whistle blowing is alerting relevant persons to some moral or legal corruption, where “Relevant persons” are those in a position to act in response.
No topic in Engineering ethics is more controversial than
whistle – blowing.
Carl Houston was a welding supervisor for a nuclear
power facility in Virginia (1970) for Stone & Weber
He saw
Improper welding procedures Use of wrong materials Welders were not trained properly The Situation was dangerous
He reported to Stone & Weber’s Manager, who ignored him. He threatened to write to Stone & Weber’s Headquarters. Shortly thereafter he was fired on trumped – up charges. Finally he wrote to Senators Howard’s Baker and Albert Gore. The Senators prompted the Atomic Energy Commission to investigate, which confirmed his allegations. Issues :
CASE 4: CITICORP BUILDING
Structural Engineer Bill LeMessurier faced a big design problem when he worked on the Citicorp Centre, N.Y – fifth highest skyscraper in New York. The 900 feet bank would rise from 9-storey (114’) high columns. The columns are positioned as follows: one at the center and the other at the CENTER OF EACH SIDE OF THE TOWER and not at the CORNERS OF THE TOWERS (as is usual) This was because of a corner of the plot belonged to a church and the church had to be accommodated there. The building was completed in 1977. An engineering student like you questioned: what will happen when the wind loading is oblique?
The Term Paper on The Chemical Engineer Engineering Engineers Work
What exactly is a chemical engineer Many would say that it is simply a "chemist who builds things" or an "engineer who makes chemicals. However, neither of these statements is completely true. The term "chemical engineer" is not meant to actually describe what it is a chemical engineer does, but to describe what sets it apart from the other branches of engineering: civil, mechanical, and ...

While LeMessurier designed welded joints, the contractor, Bethlehem Steel changed them to bolted joints. Recalculation was not done to check what the construction change would do. Wind Tunnel Tests proved that the diagonal wind loading (with a return period of 16 years) can lead to the failure of the critical bolted joints and therefore the building.
LeMessurier was deeply troubled. He considered his options
Silence Suicide
Then he told himself:
• I have information that nobody else in the world had. • I have power to effect extraordinary events that only
could initiate. He explained the problem to his client Citicorp.

The building was strengthened by welding two-inch thick steel plates over each of the 200 bolted joints. With only welding half the number of bolts hurricane Ella was threatening to strike the building. Luckily Ella’s direction changed.
Despite the fact that nothing happened as the result of the engineering gaffe, the crises was kept hidden from the public for almost 20 years. LeMessurier was criticized for
Insufficient oversight leading to bolted rather than
welded joints.
For misleading the public about the extent of the danger during the reinforcement process
For keeping the engineering insights from his peers

CASE 5. THE CHALLENGER CASE
After a lot of delays CHALLENGER’S 8th flight was set up for 28th Jan 1986 Allan McDonald of Morton – Thiokol who designed the solid–rocket booster knew the problems with the field joints on previous cold weather joints. And 28th Jan was expected to be cold.
Seal experts Arnold Thompson and Roger Boisjoly of Morton – Thiokol, explained to NASA representatives how upon launch the booster rocket walls bulge and the combustion gases can blow past one or even both of the Orings that make up the field joints. The rings char and erode, as had been observed on many previous flights. In cold weather the problem is aggravated because the rings and the putty packing are less pliable then (more brittle) Senior Vice President Jerry Mason told Bob Lund (Vice President Engineering) “TO TAKE OFF YOUR ENGINEERING HAT AND PUT ON YOUR MANAGEMENT HAT”. The managers (not engineers) voted that the seals COULD NOT BE SHOWN TO BE UNSAFE.
The Essay on Software Engineer Engineering Computer Engineers
Computer software engineers use the basics and techniques of computer science, engineering, and mathematical analysis to the design, development, testing, and evaluation of the software and systems that enable computers to perform their many different tasks. According to the Bureau of Labor Statistics, computer software engineers are projected to be one of the fastest growing occupations over the ...
The count down ended at 11.38 AM. The temperature was 36 degrees. As the rocket carrying the Challenge Rose from the ground, cameras showed smoke emanating through the O rings. Soon these turned into a flame that hit the external fuel tank and a strut holding the booster rocket. The hydrogen in the tank caught fire, the booster rocket broke loose, smashed into Challenger’s wing, then into the external tank. At 76 seconds into the flight, by the time Challenger and its rocket had reached 50,000 feet, it was totally engulfed in a fire ball. The crew cabin separated and fell into the ocean, killing all abroad. Mission Commander: Francis Scobee. Pilot: Michael Smith.
