automative lif rasise a 3500lb car 7ft above floor level if the hydraulic cylinder contain 8in diameter piston?

An automotive LIFOtraisese a 3500lb car 7ft above floor level if the hydraulic cylinder contain 8in diameter piston and a 4in diameter rod,determine the
A. work necessary to lift the car
B. required pressure
C. power if the lift raises the car 10 s
D. Descending speed of the lift for a 10-gpm flow rate
E. flow rate for the auto too descend in 10 s

Chosen Answer:

All these answers based on 8 inch lifting cylinder. You haven’t specified anything about the 4 inch rod so haven’t used that in these answers

a). work = force x distance
work = 3500 lb x 7 ft = 24,500 ft-lbs of work
————————————————-
b) 8 inch diameter piston = area of pi * r^2 = 50.26 sq inches
3500 lb / 50.26 in^2 = 69.6 psi pressure
——————————————–
c) power = work / time = 24,500 ft-lbs / 10s = 2450 ft-lb/ second
(one foot-lb /second = 0.738 watt so –> 2450 * .738 = 1,808 watts of power in SI system)
—————————————————————-
d) volume of a cylinder = pi * radius squared * height
one gallon = 231 cubic inches
10 gallons = 2,310 cubic inches
V =2,310 cubic inches = 3.14 * 4in ^2 * height
height = 2310 / (pi * 16) = 45.96 inches

So 10 gallons a minute will lift car or descend car 45.96 inches or 3.8 feet a minute
————————————————————————————————–

e) Flow rate to descend in 10 seconds instead of a minute is 6 times faster (60 sec a minute / 10 sec) = 6.
6 * 10gpm = 60 gpm

Thus, ensuring they are kept in good order at all times is actually a crucial part of this process.

One of the first things to do in this process is to make sure to only use fluoride toothpaste. This is a particular type that is designed to provide a build up defense to the teeth as well as the actual braces that are placed on them. Thus, they provide an incredible amount of protection and preventative maintenance throughout the entire process.

Then, the amount of brushing is also crucial in the entire care process. Not only should they be brushed prior to going to bed, but they should also be brushed after each and every meal. This helps prevent food from remaining lodged in the actual wiring and mechanism set in place.

What career fields can I enter into with a degree in Mechanical Engineering? What is the salary range?

What career fields can I enter into with a degree in Mechanical Engineering? What is the salary range?

Chosen Answer:

There’s a wide variety of fields you can get into with a BS in ME, depending on your interests. You can work in any of the fields previously mentioned like automotive engineering, power generation (boiler and turbine design), aerospace or manufacturing. Within those fields you can look for jobs in basic design, quality assurance, project management or even sales.

Salary range will depend on the location and type of job, obviously. On the low end, you may see offers for around ,000 per year. On the high end, in more expensive cities, you can earn up to ,000 per year. There are of course outliers on either end, but this is the typical range.

With an MS you’d be getting a little more money, about ,000 to ,000 per year and would likely be doing similar work. MSMEs are also commonly hired by large companies to do computational work like FEA (Finite Element Analysis) or CFD (Computational Fluid Dynamics). With a PhD, your starting salary would be in the -,000 range and you’d likely be doing R&D or possibly even forensic engineering in any of these areas. Of course the higher salaries that come with advanced degrees come with the disadvantges of more time in school and lost wages (not earning any money while you’re in school).

Hope this helps.

Paintings and Famous Portraits in Portrait

“One is never satisfied with a portrait of a person that one knows”. Johann Wolfgang von Goethe, famous German writer.

A portrait is a work of art that represents a specific person, a group of people or an animal. Portraits usually show what a person looks like and it also reveals something about that person’s personality. Portraits can be sculptured or painted, photographed. They really display the intensity of the subject mood.

Did you know that the earliest portraits recorded in history were the “the funeral portraits” and not the portraits of kings and famous leaders? These portraits-paintings came from Egypt. Romans continued this heritage with their sculptures. True portraits of individuals appeared in the middle Ages in Europe.

The most famous portrait of all times is ”Mona Lisa” By Leonardo da Vinci.

The portrait photography is a famous worldwide commercial industry. Many people like to have their family portraits photographed by professionals.

Portraits have been created to preserve the individuality of somebody long ago after this person is gone, as a type of souvenir.

The art of portrait have been considered like favorite hobby of many artists and for many of them the main source of living (the portraitists). Techniques for creating a portrait are different from century to century and nowadays they do have a more natural lively look.

Earlier, people loved to own famous portrait paintings created by famous artists, they used to pay a great deal of money just to have them hanged on their walls.

Nowadays, they are most impressed by famous reproductions of portraits, or even better by photographed portraits of famous people (like actors, singers, presidents, etc) that they like to have around.

PS, im just being nosey at this stage as I used to work there.

Flotation – it will be pushed through by a finance house with a lot of marketing directed at rich people and brokers. It might break cover on the net in that circumstance, close to the flotation date.

Trade sale – they’re probably negotiating privately, and have no desire to publicise the fact. The net will know nothing.

Administrator/receiver – statutory notices will come out in statutory timescales. Not sure where – might be newspaper announcements.
