SOME AMAZING FACTS OF HEART


SOME AMAZING FACTS OF HEART



  1. Cocaine affects the heart’s electrical activity and causes spasm of the arteries, which can lead to a heart attack or stroke, even in healthy people.
  2. Some heavy snorers may have a condition called obtrusive sleep apnea (OSA), which can negatively affect the heart.
  3. The heart pumps blood to almost all of the body’s 75 trillion cells. Only the corneas receive no blood supply.
  4. During an average lifetime, the heart will pump nearly 1.5 million barrels of blood—enough to fill 200 train tank cars.
  5. Five percent of blood supplies the heart, 15-20% goes to the brain and central nervous system, and 22% goes to the kidneys.
  6. The “thump-thump” of a heartbeat is the sound made by the four valves of the heart closing.
  7. The average adult heart beats 72 times a minute; 100,000 times a day; 3,600,000 times a year; and 2.5 billion times during a lifetime.
  8. The volume of blood pumped by the heart can vary over a wide range, from five to 30 liters per minute.
  9. Though weighing only 11 ounces on average, a healthy heart pumps 2,000 gallons of blood through 60,000 miles of blood vessels each day.
  10. Because the heart has its own electrical impulse, it can continue to beat even when separated from the body, as long as it has an adequate supply of oxygen.
  11. A newborn baby has about one cup of blood in circulation. An adult human has about four to five quarts which the heart pumps to all the tissues and to and from the lungs in about one minute while beating 75 times.
  12. The heart begins beating at four weeks after conception and does not stop until death.
  13. A woman’s heart typically beats faster than a man’s. The heart of an average man beats approximately 70 times a minute, whereas the average woman has a heart rate of 78 beats per minute.
  14. Physician Erasistratus of Chios (304-250 B.C.) was the first to discover that the heart functioned as a natural pump.
  15. Every day 2,700 people die of heart disease.
  16. The risk of heart disease for inactive people is double that of people who get regular exercise.
  17. The first successful heart transplant was performed in Cape Town, South Africa in 1967.
  18. The pressure created in the heart during a heartbeat is enough to squirt blood a distance of thirty feet.
  19. Each minute your heart pumps 1.5 gallons of blood.
  20. Heart disease has been found in 3000 year old MUMMIES.
  21. The BLUE WHALE has largest heart weighing over 1500 pounds.
  22. Happiness and a strong sense of emotional vitality helps lower your risk of heart disease.
  23. A normal heart valve is about the size of a half dollar.
  24. The more education you have, the lower your risk of heart disease.
  25. A good belly laugh can send 20% more blood flowing through your entire body.
  26. A man’s heart weighs about 10 ounces, while a woman’s heart weighs approximately 8 ounces.

MECHANICAL ENGINEERING TERMS 2

MECHANICAL ENGINEERING TERMS:-


1.)GEAR – A wheel with teeth that engage or mesh with teeth of another wheel.

2.)GEAR BOX– A unit which has a series of gears and shafts to vary the speed of the gearbox output shaft compared to the engine speed. This in turn increases the torque and thereby improves acceleration of the vehicle.

3.)GEAR RATIO – The ratio of the number of teeth on two gears to mesh with each other.

4.)HANDLING– The ease of maneuvering a vehicle without slipping or skidding.

5.)HYDRAULIC BRAKE – A brake system using hydraulic fluid, piston and cylinders to provide extremely high pressure for brake application.

6.)HYDRAULIC CLUTCH – A clutch that uses hydraulic pressure to actuate the clutch. Used in heavy duty equipment and where the engine is away from the drivers compartment so that it would be difficult to use mechanical linkages.

7.)HYDRAULIC CONTROL VALVES – A system of valves that senses driving conditions and automatically shifts the transmission.

8.)HYPOID GEARS – Drive pinion and ring gears whose shape allows them to mesh off centre.

9.)INDEPENDENT SUSPENSION – A type of suspension system in which each wheel is independently supported by a spring. A suspension that allows up and down movement of one wheel without affecting the opposite wheel.

10.)INNER TUBE (tyre) – The inside rubber tube assembled in the tyre casing, it maintains the air at sufficient pressure to inflate the casing and adequately support the vehicle weight.

11.)FLUID FLY WHEEL– A liquid coupling used to transmit the engine effort (torque) to a clutch and transmission. This coupling is always a major part of the engine flywheel.

12.)FORWARD CONTROL TRUCK– has the engine either in or below the driver’s cabin.

 MECHANICAL ENGINEERING TERMS 1

13.)FORWARD EFFICIENCY – is the ratio of the amount of driver input torque which is available at the wheels to turn the same to the total amount of input torque from the driver at the steering wheel.

14.)FOUR WHEEL DRIVE– Some cross country vehicles (Jeeps) have this arrangement. In this case, the engine power is transmitted to all the four wheels of the vehicle. The main advantage of this arrangement is the entire vehicle weight is available for traction.

15.)FRAME – The assembly of metal structural parts and channel sections that forms the base and supports the engine and body and is supported by the vehicle wheels.

16.)EMERGENCY BRAKE– is the hand brake, operated by a lever, is used when the vehicle is left parked and prevents the vehicle from moving. The hand brake can be applied to stop the vehicle when the service brake fails.

17.)EPICYCLIC GEAR– In the epicyclic gearing, at least one gear not only rotates about its own axis, but also rotates about some other axis.

18.)FADE (brake) – A condition that occurs when there is little braking effect with full brake pedal force.

19.)FINAL DRIVE – The final gear reduction between the engine and the drive wheels.

20.)FIXED CALIPER DISC BRAKES – Disc brakes using a caliper which is fixed in position and cannot move.

MECHANICAL ENGINEERING TERMS 1

MECHANICAL ENGINEERING TERMS:-



1.)DRAGSTER – Car especially built for drag racing.

2.)DRAG WHEEL – Special steering wheel used on some dragsters. Often consists of cross bar spoke and portion of rim on each end.

3.)DRIVE LINE or DRIVE TRAIN – Propeller shaft, universal joints etc. connecting transmission output shaft to axle pinion gear shaft.


4.)DROP CENTRE RIM – Centre section of rim being lower than two outer edges. This allows bead of tyre to be pushed into lower area on one side while the other side is pulled over and off the flange.

5.)DROPPED AXLE – Front axle altered so as to lower the frame of the vehicle. Consists of bending axle downward at outer ends (solid front axle).

6.)DOUBLE LEADING BRAKE – A drumbrake assembly with both front shoes self energized during forward wheel rotation.


7.)DOUBLE REDUCTION AXLE– In the double reduction or tripple reduction type final drive, the required speed reduction is obtained in two or more steps. This enables higher torque to be available at the road wheels. In heavy duty and off highway vehicles, multiple reduction is used. 

8.)DOUBLE TRAILING BRAKE – A drum brake assembly with both shoes self energized during rearward wheel rotation only.

9.)DRAG – To accelerate a vehicle from standing start, over course one fourth mile in length. Also used by some drivers when referring to challenging another driver to an acceleration race.

10.)DRAG LINK – A steel rod connecting pitman arm to one of steering knuckles. On some installations, drag link connects pitman arm to a centre idler arm.

11.)DIFFERENTIAL LOCK– The differential lock grips one or both of the side gears to the differential case. This prevents their rotation on the pins. This enables a larger torque to be transmitted to the gripping wheel than that to the slipping wheel.


12.)DIRECT ACTING SHOCK ABSORBER – Type of shock absorber which shortens or lengthens in action. Also called telescopic shock absorber.

13.)DIRECT DRIVE – Such as high gear when crankshaft and drive shaft revolve at same speed.

14.)DOUBLE LEADING SHOE – A drum brake having two leading shoes and no trailing shoes. Each shoe has its own actuating mechanism and pivot.


15.)DOUBLE PISTON CALIPER – A hydraulic brake caliper with two pistons and provision for applying hydraulic pressure equally to both pistons. The caliper body is fixed solidly.

16.)DASH BOARD – Part of body containing driving and control instruments, switches etc.

17.)DEAD AXLE – Axle that does not rotate or deliver power but merely forms a base upon which wheels may be mounted.

18.)DEDION – Rear axle set up in which driving wheels are attached to the frame by a central pivot. Differential unit is bolted to frame and is connected to the driving wheels by drive axles.


19.)DEPENDENT SUSPENSION – Wheel connected through an axle member so that movement of one wheel moves the other wheel.

20.)DIFFERENTIAL – A mechanism between axles that permit one wheel to turn at a different speed than the other while transmitting power from the drive shaft to the wheel axles, when the vehicle is negotiating a turn.
