Track
Why the outer edge of a road is kept higher than inner edge at a turn?
on increasing speeds the centrifugal force increases and slips the car out of its circular path.outer banks of roads are made higher so as to give and help the centripetal force to keep the car on track. stated in another aspect on increasing speeds and while taking turns the inertia of the car tends to take the car out of its path so we make the outer banks higher to counteract this inertia and give the car a margin to keep it track.
What is the term for a narrow recording band that forms a full circle on the surface of a hard disk?
track

What is Difference between inner and outer lanes of a running track?
The inner lanes of a running track are shorter in distance compared to the outer lanes due to the curvature of the track. Specifically, a standard 400-meter track measures this distance in the innermost lane, while each subsequent outer lane is slightly longer. As a result, runners in outer lanes must cover more ground to complete the same number of laps, which is why staggered starts are used in races to ensure fairness. This design accommodates the varying distances while allowing all runners to start simultaneously.
It takes ten identical pieces to form a circular track for a pair of toy racing cars If the inside of each piece is 3.4 inches shorter than the outside arc what is the width of the track?
Length of outer track = sum of length of 10 pieces = circumference of the outer circleif R is the Radius of outer circle then...Circumference of the outer track = 2pi*RSimilarly the circumference of the inner track (with radius r) = 2pi*rlength of each outer piece is 3.4 inch more than length of inner pieceSo total outer length is 10*3.4 =34 inches more than the inner length.=> Outer Circumference - Inner Circumference = 34 inches=> 2pi*R - 2pi*r = 34=> 2pi(R -r) = 34=> R-r = 34/2pi = 5.41 inches=> R-r = Width of the track = 5.41 inches1 year ago
In the hard disk o track is inner most or outer most?
The outermost track on a hard disk is located closest to the edge of the disk, while the innermost track is located closest to the center. The outer tracks have a higher data transfer rate compared to the inner tracks due to the higher linear velocity of the disk's rotation at the outer edge.
A circular race track is 3m in width a jogger runs around the inner circle of the track then at the same speed around the outer circle takin 12sec more to do so how fast does the jogger run?
The inner circle of the track with radius r meters and circumference 2πr is jogged in a time of Tseconds.The outer circle of the track has radius r + 3 and circumference 2π(r + 3) and is jogged in a time of T + 12.Speed = Distance ÷ Time.2πr/T = 2π(r + 3)/(T + 12) : r(T + 12) = T(r + 3) : 12r = 3T : 4r = TSubstituting for T in Speed = 2πr/T gives : Speed = 2πr/4r = π/2 meters per second.π/2 mps = π x 60 x 60/(2 x 1000) = 5.655 kph (3dp)The jogger runs at 5.655 kph
What is the distance traveled by a boy who walks on a circular track and reaches back to the starting point often completing one round?
The distance traveled by the boy would be the circumference of the circle, which is calculated using the formula: Circumference = 2πr, where r is the radius of the circle. When the boy completes one round on the circular track, he travels a distance equal to the circumference of the circle.
What difference might a different inner radius have on a track layout?
a shorter radius would mean a shorter track distance. The smaller the radius - the smaller the circumference.
How do you solve the curcuit board in Artemis Fowls inner circle?
you need to turn the circuit so that they form a steady track and all of the pieces connect
Are inner planets large or small?
The inner, or Terrestrial planets are very small in comparison to the outer, or Jovian planets. The smallest Jovian planet, Uranus, is 14.5 times larger than the largest Terrestrial planet, Earth.
What is the purpose of ZBR?
Zone Bit Recording (ZBR) is used by disk drives to store more sectors per track on outer tracks than on inner tracks.
Is the distance around lane 8 on a track twice the distance of lane 1?
No, the distance around lane 8 on a track is not twice the distance of lane 1. While each lane on a standard 400-meter track is wider than the one inside it, the increase in distance is not linear. The outer lanes have a longer circumference due to their larger radius, but the total distance of lane 8 is typically only about 7-10 meters more than lane 1, depending on the specific design of the track.
How do you know when your wheel bearings have gone?
When ball bearings are shot you should be able to grab the outer race or track or anything attacked to it and you will be able to twist it in relation to the inner race or track. If the bearing is perfect there will be no gimbal movement to it and it will only rotate.
