Why does a fridge door open from left to right or counter clockwise direction?

It's arbitrary. Many refrigerators (like mine) can be set up to open either way.

What simple rule has been established for finding the direction of magnetic force around a current-carrying conductor?
The right hand rule. If you were to place your right hand around the conductor, with the thumb pointing in the direction of current flow, your fingers which are wrapped around the conductor will point in the direction of magnetic flux. Said another way, if you are looking at the end of the conductor and current is flowing towards you, then magnetic flux will be counter-clockwise.
Does the crankshaft nut trun left or right to loosen?
AnswerLeft, counter-clockwise. Lefty loosey, righty tighty. --------------------------------------------------------------------------------It depends on which way the crank rotates. If it rotates clockwise the nut will be threaded on counterclockwise to prevent it from loosening. If the crank rotates counterclockwise then the nut will be threaded on clockwise.
How is it used in determining the direction of the magnetic field around a conductor carrying current?
By using right hand rulee.. how?? let me explain.. first you should be knowing the direction of flow of current, then hold the current carrying conductor by your right hand in a way that your thumb points the direction of current flowing and curl your fingures around the conductor the manner your figures curl around condutor would determine the the magnetic field's direction that may be clockwise or anti-clockwise..thankkxx.
What is the difference between left-hand thread and right-hand thread?
The difference between left- and right-hand thread is that one is turned in a given direction to tighten the fastener, and the other is turned in the opposite direction to tighten the fastener. Let's look a bit more closely.Most fasteners with threads are turned clockwise to tighten them. (This is true for a nut, and for a bolt, you'd be looking at the head with the threads away from you.) These are right-hand threaded fasteners. These fasteners are turned counter-clockwise to loosen them, as you might have guessed. With left-hand fasteners just the opposite is true when tightening them or loosening them.We make left hand fasteners for special purposes. We'd have to have a reason to make "backwards" threads on a fastener, wouldn't we? We do, and most applications where we see left-hand threaded fasteners involve attaching rotating parts. A lawn mower blade is a good example, and by looking at the physics, it will become obvious.A lot of blades on lawn mowers attach to the shaft of the motor with a nut or a bolt. You know the machine we're talking about. The motor shaft points straight down, and the blade is a "cutter bar" with the ends sharpened. Anyway, if the motor on the machine turns clockwise (looking at the motor from the bottom where the blade is attached), using a fastener that turns clockwise to tighten it (a right-hand threaded fastener) sets the stage for a problem. Roll up your sleeves and look at the physics.When the motor starts, it "torques" the shaft clockwise. The blade and the fastener that hold the blade are likewise torqued clockwise. But consider mean old inertia. Inertia is the name we give to the phenomenon associated with objects that have mass (like the fastener that holds the blade on). If a body is at rest, it wants to remain at rest. If it's in motion, it wants to remain in motion. Force is necessary to change the motion of a mass because of inertia. That said, let's focus on the bolt that holds the blade on the motor.If the bolt on the motor shaft of a lawn mower turns clockwise and a right-hand threaded bolt holds the blade on, the inertia of the bolt when it's at rest makes it "resist" the torque of the motor, which is clockwise. The effect on the bolt is that the bolt's inertia makes it want to turn counter-clockwise. And counter-clockwise is the direction we'd turn the fastener to take it off. If the motor is started time and time again, it applies a little torque in the "wrong" direction to the bolt that holds the blade on. If the bolt ever becomes a bit loose, it can easily be spun off, which will cause the blade to detach. If the blade comes off while the machine is running at speed, that blade becomes a lethal projectile.Left-hand threads are applied in a number of applications, and most involve rotating parts. It costs more to make left-hand threaded fasteners because the volume in which they are produced is lower. The economy of scale makes the right-hand threaded fasteners cheaper, and they would be a manufacturers choice if not for the engineering considerations associated with the rotating parts of a machine. Left-hand threaded fasteners are made for a specific application where right-hand threaded fasteners would be a fool's choice.
Do jet engines airplanes have a critical engine?
With the above mentioned answer, it is pretty much correct except for the twin engine aircraft. For the twin engine aircraft, the critical engine is the one that produces a thrust line closest to the fuselage. Example: if the twin engine aircraft is equipped with 2X engines which have the propeller rotating in a clockwise direction, then the left engine will be the critical engine. This is because the down going blade on the left engine will produce a line of thrust closest to the fuselage compared to the right engine's propeller. So it is safe to say that if the left engine fails, the aircraft will be harder to control because the thrust line produced by the live engine on the right side has a longer arm from the fuselage causing a higher moment wanting to yaw and roll the aircraft to the left which is harder to control compared to if the right engine fails, such as the Piper Twin Comanche aircraft. However, if the twin engine aircraft is equipped with counter rotating propellers, meaning, the left engine prop rotating clockwise and the right engine propeller rotating counter clockwise, then there is no critical engine, because both down going blades of the propeller produces a thrust line both equal in distance from the center of the fuselage.
What does counter clockwise means in math term?
Counter clockwise means that a curve has "positive orientation". You are traveling in a counter clockwise direction if the "interior" of the curve is on the left of the direction you are traveling. You are traveling in a clockwise direction if the "interior" is located on the right. This notion of direction is important when doing certain advanced calculations, such as line integrals - evaluating in the wrong direction will possibly give you a negative answer!
What is counter clockwise?
Clockwise goes right in a circle, counterclockwise goes left in a circle.
What is counter-clockwise?
Counter clockwise is the opposite to clockwise , so if you think of a clock and it goes right , counter clockwise is the other way round so it's going left.
Which direction is clockwise?
To the right
Is the oil drain plug on a 2006 pt cruiser left or right hand thread?
right hand, turn counter clockwise to loosen.right hand, turn counter clockwise to loosen.
What is the meaning of clockwise?
it refers to the way in which things move. clockwise means the direction that the hands on a clock turn. counter clockwise means the opposite way the hands turn on a clock
Which direction does the earth revolve around the earth?
The earth revolves counter-clockwise if observed from the north. as he is right you could also tell on the constellations.
What is the difference between a clockwise and an anti-clockwise rotation?
Clockwise turns to the right, counter-clockwise turns to the left
What is the proper direction to traverse a cul-de-sac in Kentucky?
Same way as it is in any country which drives on the right - right to left, a.k.a., counterclockwise.
Why do quadrants on a coordinate plane go counter clockwise?
Because angles, which start at 0 degrees, travel in that direction. When an angle is at 0 degrees, it is located to the right of the y-axis, and on the x-axis. As the degrees grow larger, the angle unfolds to the left, or counter-clockwise.
Angle in clockwise direction?
right angle
Left or right to take off the oil filter on jeep liberty 2009?
To the best of my knowledge, all filters loosen by spinning in the counter-clockwise direction.
