.Q21 The forces do not cause rotation

True Story! The 1998-1999 Mars Climate Orbiter mission was declared a total loss in1999 as there was a unit conversion mismatch error between Lockheed Martin and NASA. Themismatch was in the thruster force units. NASA used the SI system which called forNewton-Seconds (4.45 times as large) of thrust and Lockheed Martin used Pound-Force Seconds.Calculations placed the Orbiter at 68 miles from the surface as it went into orbit, but it waswithin 57 km of the surface after the breaking maneuver. Any distance from the surface lessthan 50 miles would have caused the Orbiter to crash.a. What was the actual distance of the Orbiter from the surface in miles?b. In percentage, how far off from the calculated 68 miles was the Orbiter?

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 their concerns.  Several people mention…

It shows the four basic steps in a 4-stroke internal-combustion engine that are usually found in cars. Based upon what you have learned, explain why, in the 3rd step, the explosion forces the piston down.

Shannon’s Law Arizona statutes were changed in 2000 concerning the use of firearms. The statute was named after a fourteen-year-old girl, Shannon Smith in Phoenix, Arizona who was killed by a stray bullet in June 1999. Shannon’s law was only a misdemeanor until the statutes changed in 2000. It is now a felony to discharge a firearm randomly into the air.  No arrests were ever made for the death of Shannon Smith. She was standing in the middle of the back yard talking on her cell phone when a stray bullet went through the top of her head and killed her. Q: A number of injuries and deaths have been attributed to celebratory gunfire both in the U.S. and worldwide. In the state of Arizona, one such tragic incident led to the death of an eighth-grade student as described in the accompanying graphic. if you model the round that struck Shannon as a lead sphere 9mm in diameter (a common handgun caliber) and accounting for buoyant force: Calculate the probable velocity of the round that caused…

Automobile repair shops typically recommend that their customers change their oil and oil filter every 3,000 miles. Your automobile user’s manual suggests changing your oil every 5,000–7,000 miles. If you drive your car 15,000 miles each year and an oil and filter change costs $30, how much money would you save each year if you had this service performed every 5,000 miles?
