The plane was having engine problems from Florida to South Carolina. The magneto in one of the twin engines was bad. The pilots informed the band and crew it was safe to fly on one engine to Baton Rouge, LA where a mechanic was waiting to repair the faulty engine. On Oct. 20, 1977 near McComb, MS , the pilots switched the fuel to burn richer thus causing them to run out of fuel and crash.

An ideal truss has pin joint connections, allowing laod to be taken only in tension and not in bending or shear.

In reality, truss joints are not pinned, and do carry some moment and shear, but because tensile stiffness dominates, the moments and shears are small and called secondary.

The hydraulic lift was invented by Leon Edoux.

A potentiometer is another name for a variable resister used for voltage dividing. Potentiometers have three tabs on them The two outer most tabs have the full resistance of the device across them. The center tab is connected to the wiper that slides across the surface of the resister. A voltage is applied to the two outside tabs on the potentiometer. A voltage of your choosing will appear across either the left tab to the center wiper tab or from the right tab and the center wiper tab. A potentiometer of this type is used to control the speed output of variable frequency drives. A 10K potentiometer has 10VDC applied across the two outside tabs If the drive sees the full 10 volts it allows the drive to go to full output and the motor will run at full speed. With the potentiometer's center tab wiper at half position a voltage of 5 VDC will appear to the drive. When the drive sees the 5 volts it tells the drive to go to half speed output and the motor will run at half speed. This potentiometer is linear so no matter where the wiper is positioned, the motor speed will follow the potentiometer settings from 1% right up to 100%

• 10 gauge: 3.57 mm
• 11 gauge: 3.18 mm

The portion between the fulcrum and the effort applied in a lever is called effort arm.

There are many differences, and here are a few:

Pneumatic systems use gasses which are compressable - hydraulic uses liquids that are non-compressable.

Hydraulics' motion is slow and smooth - pneumatics' motion is quick.

Pressure can range from 500 to 5000 psi - pneumatics operate at around 100 psi.

it was made out of wood

and the inventor got the idea from his daughter when she knocked over the wheel from there spinning wheel and the wheel kept on going so this lead to the spinning jenny its just like a spinning wheel it just dose more thread at once and its faster and it was a times saver back in the 1700s or 1800s

It's a spinning wheel - you can use it to make yarn. is a spinning whell you cna use it to make yarn, and ya

the pulley was invented in ancient Sicily around 250 BC.

The ancient Egyptian wooden four lobe pinion pulley was used to construct the Giza Pyramids around 2600 BC.

This pulley surrounds its load and is unlike anything in the modern world.

It operates with a mechanical advantage of 2.8 (MA=2.8) on the CLASS 2 lever principle.

When hoisted the pulley with load rotates and climbs stepped structures with positive engagements of pulley lobes with steps.

This is earliest machine known using "rack and pinion" mechanical technology.

Yes, The Shaduf was used. A Shaduf is what the Egyptians used to collect water.

The F-15 Eagle is one of the worlds fastest operational fighter jets with a top speed of Mach 2.5.

The Lockheed YF-12 interceptor, one of the predecessors of the SR-71 "Blackbird" was approved for acquisition by the USAF back in the 1960's, but due to government intervention the order for 100 planes was canceled. The YF-12 was reportedly capable of Mach 3.35.

gymnastics,water technology ------------------------------------------------------------------------------------ The steam engine was invented by Heron, an ancient Greek geometer (mathmatecian who specialized in geometry) and engineer from Alexandria. Dikaiarch of Messina (350-290 BC) a Greek geographer introduces to the map making world the notion of latitude and longitude. There are many other inventions, sech as the water screw by Archimedes, which would move water upward or downward in a corkscrew motion.

Air Force One is the call sign used describe any aircraft carrying the US President, so in theory Air Force One could be any type of aircraft.

The official Presidential fleet consists of two customised Boeing 747s, either of which may be colloquially referred to as Air Force One. However this only becomes the official designation when the President is on board.

Galvanized wire ropes, have more strngthen tensile. Safety factor is 5.0 for gantry and over head cranes. Galvanized wire ropes, prevents from rust and moisture. Non galvanized wire ropes, are coated with zinc, which may get rust during atmospheric condition. Galvaum wire ropes have a combination of Zn+al.

AutoCAD (Computer-Aided Design) is a widely used software tool in the field of engineering for creating, modifying, and documenting detailed design drawings and models. Its versatile capabilities make it an essential tool across various engineering disciplines. Here are some common uses of AutoCAD in engineering:

1. **Architectural Design:** AutoCAD is frequently used by architects to create precise and detailed floor plans, elevations, sections, and 3D models of buildings and structures.

2. **Civil Engineering:** Civil engineers use AutoCAD to design infrastructure projects such as roads, bridges, highways, dams, and drainage systems. AutoCAD's tools help in creating accurate plans, profiles, and cross-sections.

3. **Mechanical Engineering:** AutoCAD is extensively used by mechanical engineers for designing parts, components, and assemblies. It aids in creating 2D drawings and 3D models of machines, equipment, and mechanical systems.

4. **Electrical Engineering:** AutoCAD is used by electrical engineers to design electrical systems, wiring diagrams, circuit layouts, and panel layouts. It helps in creating detailed schematics for various applications.

5. **Structural Engineering:** AutoCAD is used to design and detail structural components of buildings and structures. Engineers use it for creating accurate drawings of beams, columns, foundations, and other elements.

6. **Industrial Design:** AutoCAD is employed in industrial design for creating product concepts, prototypes, and detailed manufacturing drawings. It aids in visualizing and refining designs.

7. **Aerospace Engineering:** AutoCAD assists aerospace engineers in designing aircraft components, interiors, and systems. It aids in creating detailed plans for various aircraft parts.

8. **Environmental Engineering:** AutoCAD is used by environmental engineers to design and plan environmental systems, including water treatment plants, waste management facilities, and pollution control systems.

9. **Surveying:** AutoCAD is used in land surveying to create accurate survey plans, contour maps, and site layouts.

10. **Urban Planning:** Urban planners use AutoCAD to design urban layouts, land-use plans, and zoning maps.

11. **Geographic Information Systems (GIS):** AutoCAD can be integrated with GIS data to create and edit spatially accurate maps and geographic information systems.

12. **Construction and Project Management:** AutoCAD drawings serve as the basis for construction projects, facilitating communication among stakeholders and guiding construction activities.

13. **Prototyping and 3D Printing:** AutoCAD's 3D modeling capabilities are used for creating prototypes and models that can be 3D printed.

14. **Documentation:** AutoCAD is instrumental in creating detailed documentation, including technical drawings, plans, sections, and specifications.

AutoCAD's flexibility, precision, and efficiency make it an indispensable tool in the engineering industry. It enhances design accuracy, reduces errors, and facilitates collaboration among multidisciplinary teams working on complex projects.

Yes you can, although some more eaisily than others as they all have different melting points. To find out the exact melting points you can google, for example:: 'Melting point of Iron'

Melting metals is quite commonly used in industries to shape the metal into a mould, which is called 'Casting'.

WCB stands for "Wrought Carbon" with Grade B.

There are 3 kinds of Grade; A,B & C which define the ductility & tensile strength.

Grade B has very good ductility & tensile strength as compare to Grade A & C.

The combination of carbon and stainless steel.
