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 opposite of elastic?
The opposite of elastic is inelastic, where a material cannot stretch and rebound. A material without this quality could be "inflexible" (rigid, stiff) or one that did not rebound, termed "plastic" (deformable).
Elastic suggests that the material recovers its original shape after an applied load is removed. Plastic means that it doesn't recover its shape. Steel is an example of an elasticmaterial, when it is loaded within its capacity. It becomes plastic if it is overloaded. Concrete can be considered an elastic material only in compression.
Are there readily available substitutes for gold in industrial applications?
6 week old turds have the same properties as gold. Try it out.
How do we can calculate weld deposition rate for submerged arc welding?
Check wire feed rate of saw wire (metre/min.)with this we can check deposition per minute.
by multipling this with 60 , we can get deposition per hr.
How do you install a hockey puck lock on a express van?
---- Hey, I hate to tell ya' but drilling is the easiest way and the only way unless you want to weld it on. my e-150 has locks on the side and rear with a weather-guard bulkhead behiend the seats. trust me there worth it.
How cooling tower height is significant for cooling tower design?
There's quite multitude of things that impact a cooling performance. Specifically the height of the tower impacts on the the drafting air through the tower. See "Air Cooled Heat Exchangers and Cooling Towers" by Kroger for something more indepth.
What is mean by Blowing factor in steam blowing?
Disturbance Or Correction or K Factor in steam blowing in Power Plants is the ratio of Drag created during steam blowing to the drag occurring during Maximum Continuous Rating.
Equation of disturbance factor K is shown as below: K=ΔP1/ΔP2
ΔP1=PD1－PS1；ΔP2=PD2－PS2
ΔP1:Difference pressure of steam drum and corresponding super heater during steam blowing-out.
ΔP2: Difference pressure of steam drum and corresponding super heater in normal operation of boiler
What is the Wall thickness for schedule 80 4 black iron pipe?
The wall thickness of 4" Sch 40 pipe is 0.237 inches.
The outer diameter is 4.5 inches and the inner diameter is 4.026 inches.
What is spring loaded inverted pendulum?
The Spring Loaded Inverted Pendulum (SLIP) model is an attempt at describing running motion through a spring-mass model. The SLIP model is depicted as an energy conserving system with a point mass as the body and a massless spring as the leg and foot.
The deformation rates as high as A 2m s b 25m s c 250m s d 500m s are used in high velocity forming of metals.

What are the elementary parts of a vibrating system?
spring
mass
dashpot (viscous damper)
with these you can model any vibrational system via
mx''+cx'+kx=f(x) where f(x) is the exciting force
To stop electrolytic action causing corrosion. Dissimilar metals (especially steel and aluminium) form a battery when wetted with water. This battery will cause a small current flow in the metals which will then eat away at the aluminium. Coating one or the other components, provides an insulator, which stops the battery forming.
The ports of the angle valve ( Inlet and outlet) are oriented at an angle 90 deg.
The choice of MPA (Marine Protected Area) depends on your needs, such as research, conservation, or recreational purposes. If you're looking for specific data, consider using online databases or resources provided by organizations like NOAA or WWF. For navigating or exploring, tools like Google Earth or specialized marine mapping applications can be helpful. Always ensure the MPA aligns with your objectives and local regulations.
it i simply a projectile motion
assuming the vertical component zero
apply the equation
y=(1/2) (g) (t2 )
y=height
g=9.8
if we did not assume the data is in suffcient to calculate the time
Why do rockets have a Diverging Nozzle at the exit?
To increase the exhaust velocity.
+++
Pressure, not velocity. A gas flowing through a divergent nozzle gains pressure at the cost of speed.
Was titanic sank because of charpy v-notch test was not done?
It is unlikely that an impact test of the metals used in the Titanic was responsible for it's sinking. Had the test been done and it's impact resistance been proved, the problems of designing a liner which could travel at 20 knots into a solid lump of ice with a mass of millions of tonnes would be impracticable.
The most obvious cause of the sinking rests with the water tight compartments which were not sealed at the top allowing water from the puncture in the skin to flow over into the next water tight enclosure slowly dragging the vessel under.
How do you calculate weight of hollow cylinder?
In order to Calculate the weight of a hollow cylinder, you need to find out the density of the material of the cylinder first. once you have that, you can use the formulas below
Find out volume of material as follows:
Volume = Pi * (Outer Diameter of Cylinder)2/4 - Pi * (Inner Diameter of Cylinder)2/4
Mass = Density * Volume( from above equation)
Note: Remember that units of Density and volume should be matching.
