In an engine, work is done through the conversion of fuel's chemical energy into mechanical energy. This process typically involves combustion, where fuel ignites and produces high-pressure gases that push against pistons. The movement of these pistons then turns a crankshaft, which ultimately powers the vehicle or machinery. The efficiency of this energy conversion directly affects the performance of the engine.

What is work done?
Work done is used as a term to communicate that a predetermined task has been completed OR to specifify a percentage of the task completed by saying that work done is at (f.i.) 70%
How does Thermodynamics affect the work of mechanical engineers?
thermodynamics, is essential for mechanical engineers, because the subject is mainly about heat and work in system, and as an engineer that is important, especially when you have to design engines, because that is when you have to determine important factors such as the amount of work that can be done by that engine internally, and the heat it transefered and obtained.
What occurs in a steam engine?
Water is heated to produce steam. The steam is used to power the engine. The power from the engine does the work or powers other instruments that do the work.
Can work be done on a system if there is no motion?
no
How calculate the engine work from pressure crank-angle diagram?
Well Work is the integral of P*dV and since the crank angle plot doesn't directly show volume you need to calculate instaneous volume of the cylinder as a function of crank angle. If you know the bore and stroke you can find the volume of the cylinder and you can relate this to the crank angle. Once you have these values you can replace the crank angle with volume and have a P-V plot or pressure on the y-axis and volume on the x-axis. Then you can integrate the area under the curve and find the work from the engine. However, all this is done for you if you can find the P-V diagram for your engine or engine cycle (Sterling, Atkinson, Otto, Diesel, etc.) and integrate this for the work.
The amount of work done by heat engine equals the amount of what?
The amount of work done by a heat engine equals the difference between the heat input and the heat output of the engine. This is known as the heat engine's thermal efficiency.
How did work done by the steam engine compare to work done by horses?
the steam engine was quicker and stronger than hoses
How did work done by the steam engine compare to work done by the horse?
steam engine was quicker than horses and stronger than horses
How much work is done by the heat engine if it takes in 2000J of heat and rejects 1500J of heat?
Work done=Heat in-Heat out 2000-1500=500J
Is work done if you push a car that has run out of gas?
Yes. The work is being done by whoever is pushing rather then the engine, but work is being done. Any time a force is applied through a distance, work is being done.
How do engine swaps work?
You take one engine out of a car and put another one in. Done.
How did the work by the steam engine compare to work done by horse?
steam engine was quicker than horses and stronger than horses
Is work being done by an automobile operating for several minutes?
No work is being done by the automobile if it is standing still with the engine running since it isn't in motion (not counting any work done by the vibrations transmitted to the air and ground upon which it rests). The engine, on the other hand IS doing work while idling since the parts inside are moving and both having work done on them and, in turn, performing work on other parts.
The amount of work done by a heat engine equals the amount of thermal energy?
The amount of work done by a heat engine is not equal to the amount of thermal energy it absorbs. In a heat engine, only a fraction of the thermal energy absorbed is converted into work, with the remaining energy typically being expelled as waste heat. The efficiency of a heat engine is a measure of how effectively it converts thermal energy into work.
How fast can work be done by a 5 hp engine?
A 5 horsepower (hp) engine can do work at a rate of approximately 3,730 watts (since 1 hp is equivalent to about 746 watts). To determine how fast work can be done, you can calculate the amount of work done over time. For example, in one hour, a 5 hp engine can perform about 13,560,000 joules of work (since 3,730 watts multiplied by 3,600 seconds equals 13,428,000 joules). Therefore, the speed at which work is done depends on both the power output and the time it operates.
How does the amount of work done on an automobile by its engine relate to the energy content of the gasoline?
The amount of work done on an automobile by its engine is directly related to the energy content of the gasoline used as fuel. Gasoline contains potential energy stored in its chemical bonds, which is released during combustion in the engine to produce work that moves the vehicle. The higher the energy content of the gasoline, the more work can be done by the engine.
How expensive is it to re-ring an engine?
If you do all the work yourself, it can be done for a couple hundred dollars.
