An engine is used to lift a beam weighing 9800 n up to 145 m how much work must the engine do to lift this beam?
WORK
Solution1.This is what you know:
force: F =9800 n distance: d =145 m2.This is what you need to find out:
work: W = ? J3.This is the procedure you need to use:
Substitute the known values f= 9800 n and d = 145 m into the work equation:
W = Fd = (9800 N)(145 m) = N·m = 1421000 J4.Check your answer:
Check your answer by dividing the work you calculated by the distance given in the problem. The result should be the force given in the problem.
What else can I help you with?
The vertical travel distance of a intake or exhaust valve is called the?
The vertical travel distance of a intake or exhaust valve is called the lift. Valve timing and lift is critical for a properly running engine.
What is the difference between elevator lift and crane lift?
The way they lift the load.
How can you tell it's an interference engine or If it's a non-interference engine?
If you give the yr/make/model/engine, could let you know... But if you want to find out your self. You need to turn piston 1 to TDC and depending on the engine, undo the valve spring keeper and measure how far the valve drops until in hits the piston. Subtract .050 of an inch and if it is less than the max valve lift you have an interference engine.
To lift the engine 3 meters the operator must pull a total of 30 meters of chain through the pulley system?
Yes, I am pretty sure that such pulley systems exist.
What size you i beam can safely span 40 feet with 1000lb capacity in the middle?
This is one of those questions that no one will will tackle because there are other factors that weigh into this type construction: Angle of lift, How will the new beam be supported, Is the foundation sufficent, indoors vs outdoor ect. Your safety is important, and you would be better served to discuss your needs with a engineer that can look at the whole picture. I built a overhead crane once with a 40' span once and I can tell you from experience you will not find a beam straight enough as delivered. It will have to be proffessionaly straightened. Mine was a 24 x 100# I-beam and it had a 18" bow that had to be corrected.
How much work must be done to lift the beam 290m?
The amount of work done to lift an object is equal to the force applied multiplied by the distance over which the force is applied. Without information about the force or mechanism used to lift the beam, it is not possible to calculate the work done.
What is the horsepower requered to lift 1000 kilgram one meter in one second?
On earth, force required to lift 1000 kg is 1000kg*9.8ms-2 = 9800 NIn joules, work done = 9800N*1m = 9800 JPower = 9800J/1s = 9800 W1 horsepower = 746 WSo power = 9800/746 = 13.13672922252011 horsepower
How much power is used to lift a barbell weighing 1250 in 2m 3s?
10p
What happens when a man weighing 175 lb attempts to lift a heavy object?
When a man weighing 175 lb attempts to lift a heavy object, his muscles will need to generate enough force to overcome the weight of the object. If the object is too heavy for his muscles to lift, he may strain or injure himself. It is important to lift heavy objects using proper lifting techniques to prevent injury.
How you Design a pulley rope system to lift 700kg beam to the height of 4m?
Nice try
How do you lift a 100kg steel beam 3 ms off ground?
To lift a 100kg steel beam 3 meters off the ground, you would need to apply enough force greater than the force of gravity acting on the beam (100kg * 9.8m/s^2) to lift it against gravity. This can be achieved using a lifting device like a crane or forklift that can provide the necessary force while ensuring safety protocols are followed.
How much work in joules must you do to lift an elephant weighing 60000N up 1.5m onto the back of a truck?

How much pressure is required to lift one ton?
Assuming you need a metric ton, that's 1000 kilograms. To lift that, you need a FORCE of 9800 newtons. Force is related to pressure by: pressure = force / area, so the answer to the original question would depend, over what area the force is applied.
What the purpose of plane engine?
The engine helps the plane to fly by proiding thrust and lift.
What is the name of the instruments used for lifting up an engine in a car?
motor or engine lift
