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 happened to the ultimate tensile and yield strength of most of the metals when temp falls?
building will collapse due to steel failure
What is the difference between tractor and car?
Size, weight, towing capacity, torque, engine size, speed, transmission and purpose just to name a few. Tractors also have extra parts not found on cars, such as hydraulic hookups.
100 gauge polythene thickness means how many thicness in mm?
ANSWER
In the case of polythene, gauge can be converted to thickness by dividing by four to get the thickness in micron or dividing by 4000 to get the thickness in mm. Here are some common examples:
100 gauge = 25 micron = 0.025mm
120 gauge = 30 micron = 0.03mm
200 gauge = 50 micron = 0.05mm
250 gauge = 62.5 micron = 0.0625mm
400 gauge = 100 micron = 0.1mm
How can mortality be the creation of the Shaper?
In certain philosophical and literary contexts, mortality can be viewed as a creation of a Shaper—a divine or creative force—representing the inherent limitations and transience of life. This perspective suggests that mortality instills meaning and urgency in human existence, prompting individuals to seek purpose and fulfillment. By imposing mortality, the Shaper encourages growth, creativity, and the appreciation of life’s fleeting moments, ultimately shaping human experience. Thus, mortality becomes a crucial aspect of the human condition, fostering connections and a deeper understanding of existence.
G = giga
Pa = Pascal (a measurement of pressure or force)
1 GPa = 1000 MPa = 1 000 000 KPa = 1 000 000 000 Pa
1 GPa = 10,000 Bars = 145,037.74 psi = 9,869.2327 ATM = 7 500 616.8 mmHg
What is the importance of combustion?
what is the importance of these reaction
- combustion
- corrosion
thank you Emma
- Shear lugs are small steel members welded or brazed to parent structural members prior to encasing them in concrete or other material. These lugs hold this encasing material with the steel member for environmental protection and also give the desired shape to the structural members.
- Anchor bolts are the ones which are fixed with the parent structural member to hold or support external objects/loads to the parent member. Fixing can be chemical or mechanical depending on the material on which it is anchored.
Impulse refers to both force and?
Impulse refers to both force and time.......
Impulse=(the change in Force)*(time)
OR
Impulse=the change in Momentum
A main shaft turbine is a type of turbine where the rotor is directly connected to a central shaft that transmits mechanical power. This design is commonly used in large-scale power generation, such as in steam or gas turbines, where the main shaft converts the energy from fluid flow into rotational energy. The main shaft is a critical component, as it supports the rotor and facilitates the conversion of energy to produce electricity efficiently.
The derivative of cos(x) is negative sin(x). Also, the derivative of sin(x) is cos(x).

Modern U.S. submarines are built by what is known as "Modular" construction. In the early days of Nuclear boats, construction was like any Navy vessel - from the keel up. However, with the advent of the Trident FBM submarines modular construction was developed, and found to be much more advantageous.
Essentially, each major compartment is built individually in separate sections. When completed to a certain point, the sections are brought together (they're constructed on a rail system) and then welded together. All systems are connected as the compartments come together. Seeing each section being built at the Shipyard is a real sight to behold, but not as much as seeing a Trident Submarine on the rails next to an LA class boat. What you actually see above water is only about 1/5 of the boat's actual size - most of it is underwater.
This construction method is much faster than the old way, and is just as strong. Use the link below to see an image of a module of a UK Astute class submarine on its way from a builder to the yards.
Why do you measure effective diameter of a screw thread?
the difference between the min and max effective of your two threads will tell you if there going to clash on assembly
Is the ideal mechanical advantage of the ramp is it's mechanical advantage with friction?
No, the ideal is without friction.
