Mechanical Engineering
Mechanical Engineering is a branch of engineering that encompasses the generation and application of heat and mechanical power and the design, production, and use of machines and tools. Mechanical engineering involves application of the principles of dynamics, control, thermodynamics and heat transfer, fluid mechanics, strength of materials, materials science, electronics, and mathematics.

What is tHe purpose of inlet guide vanes in gas turbine?
In axial flow compressors, the primary purpose of IGVs (fixed or variable) is to guide the airflow onto the first stage rotor blades at an appropriate or required angle of attack.
What is the difference between s355jr st52-3?
would you tell me the difference Material quality between St-52 and S355JR
Why should adjustable wrenches not be used on fasteners?
They lack the close fitting measurements that a dedicated tool would have . They also have a tendency to 'round off' the corners of the fastener itself due to a poor fit .
Why is your carburetor back firing on your 1978 American clipper rv?
Could be in need of a tune up and/or a carburetor rebuild (accelerator pump failure).
here is a website that tells you exactly how to make one, step by step...... www.instructables.com hope it helps
A control plan is a documented strategy that outlines the steps and procedures for monitoring and controlling a process to ensure that it meets quality standards. It typically includes key parameters, measurement methods, monitoring frequency, and actions to be taken in response to deviations. Control plans are commonly used in manufacturing and other industries to maintain consistency and quality in production.
What is the abbreviation of SFA in filler rod spec in welding?
SFA stands for Steel framing alliance Cheers T. Mathew mathew@harimachines.in
A septic system is used to filter waste water so it is restored to an acceptable level so it can be distributed back into the environment. A G5 septic system is a subcategory of septic systems. It is used to specify which uses are permitted in a specific community. All property owners have to follow these guidelines.
Name and describe two types of outside caliper?
A vernier caliper has a moving jaw and a fixed jaw. The moving jaw has marks to set against the ruled divisions on the stem of the fixed jaw. A micrometer caliper has a micrometer clock gage whose hand turns to provide the fine divisions added to the marked scale.
What is the theoretical max speed of a helicopter?
The theoretical max speed of a helicopter is based on the speed of the main rotor through the air, since conventional airfoils essentially quit lifting at close to the speed of sound. Knowing that, let's assume the main rotor's tip speed moves through the air at 400 mph while in a hover. Now, as the vehicle begins to move forward, that forward motion is added to the existing tip speed. Since the speed of sound at sea level is around 750 mph, our example bird shouldn't be able to go any faster than 350 mph. Realistically, our example wouldn't be able to travel even that fast, since air traveling across an airfoil (the main rotor) accelerates across the top surface, thus cutting into our theoretical top speed. That being said, airfoil design is constantly evolving, allowing incremental improvements in efficiency, speed, and noise reduction.
Where do you install a pressure equalizing valve?
Need more info - what is it for? What is the size of the pipe and the pressure differences you are trying to get?
The wrod pneumatic deals with the pressure and air control ....now according to newtons law...f=ma; we can add a relay to pneumatic, a relay is a electromagnetic switch which connects to circuit and control the flow elctricity....in the circuit.....thus , by reading the above theory we can estimate that what pneumatic relay is exactly....
no claps for me,,,,,,
thank u..
What type of valve for incoming water service gate or ball valve?
Ball valve is usually preferable. full flow with no restriction and a lot easier and faster to turn off when needed.
Where can you get an adapter for 4412 carb. to 4brl Chevy cast iron intake?
#1932 Mr Gasket will fit. Available at Autozone.
Can you replace the insides of a gate valve?
Most certainly BUT it has to be replaced with the same type of disc and spline
Analysis of forces on horizontal milling machine?
how to calculate forces on coulmn of horizontal milling machine?
Nyloc nuts are made of metal like other nuts but they have a nylon insert to resist unwanted rotation.
What is the difference between hydraulic motors and pumps?
A hydraulic pump uses an external mechanical force to pressurize the hydraulic fluid. A hydraulic motor uses the pressurized hydraulic fluid to apply a mechanical force an external machine.
See the difference between a pump and a motor.
How do hydraulic cranes bleed the hydraulic system?
With interchangeable rubber washers and bushes and ball bearings can make the bleeding stop.
Why metals break on dynamic load but not on static load of same magnitude?
That isn't necessarily true. If the metal is under repeated dynamic loading, it becomes a matter of material fatigue and not strength. For instance, if you bend a paper clip back and forth repeatedly, it becomes easy to break. The material properties have changed (more brittle) due to the repeated dynamic load.
In the case of impact or blast loading, it is actually the opposite. Materials often have the ability to withstand much larger loads than they could statically, but for very short durations (on the scale of milliseconds).
because i said so.
Dynamic load- Any load which is nonstatic, such as a wind load or a moving live load.
Static Load - Any load, as on a structure, which does not change in magnitude or position with time
