What is the radius of one wheel on a truck that turns 330 times in a one mile trip?

1 mile = 5280 feet
The wheel turns 330 times in 1 mile ie 330 times for 5280 feet
So each turn of the wheel = 5280/330 = 176 feet.
So, if r is the radius of the wheel, its circumference is 2*pi*r
and 2*pi*r = 16 feet
so pi*r = 8 feet and r = 8/pi feet = 2.55 feet.

When does a wheel and axle have a mechanical advantage greater than one?
When the radius of the wheel is larger than the radius of the axle - which is almost always true.When the radius of the wheel is larger than the radius of the axle - which is almost always true.When the radius of the wheel is larger than the radius of the axle - which is almost always true.When the radius of the wheel is larger than the radius of the axle - which is almost always true.
What is the mechanical advantage of a wheel and axle?
The mechanical advantage of a wheel and axle is the ratio of the radius of the wheel to the radius of the axle.
Which factor of both the wheel and the axle can be used to calculate their mechancical advantage?
the radius of the axle and the radius of the wheel
The radius of the wheel is 12 inches What is the approximate circumference of the wheel Please help?
Multiply the radius by 2 x pi.
What is the mechanical advantage of a a wheel and axel?
The mechanical advantage of a wheel and axle is the ratio of the radius of the wheel to the radius of the axle. Ex:- Suppose the radius of the wheel is four times greater than the radius of the axle, every time you turn the wheel once, your force will be multiplied four times.
If the radius of a wheel is 0.6m how far would the bike travel in 40 turns of the wheel?
get the circumference of the circle using 2*pi*r (1.2*pi) times that by 40 to get the answer (48*pi)
How many turns must a bicycle wheel make of radius 0.5m make to travel a distance of 100m?
A wheel with a radius of 0.5m has a circumference of 2πr metres. In this example, 2πr = 2π x 0.5 = π metres. The wheel makes 100/π turns when travelling 100 metres, that is 31.831 turns.
Why does your truck pop when you make sharp turns?
possibly your front wheel axle.
When wheel B turns 2 revolutions, wheel A turns 5 revolutions. When wheel A turns 40 revolutions, gown many revolutions does wheel B turn?
40 / 5 = 8 8 * 2 = 16 Wheel B turns 16 times.
How many times a wheel of radius 28 cm must rotate to cover 704 m?
With one rotation, the wheel advances one entire circumference.The circumference is radius times (2 x pi).To convert from centimeters to meters, divide by 100.Finally, just divide the total number of meters by the circumference (in meters), to get the number of turns.
How many times a wheel of radius 28cm must rotate to go 352m?
200 TIMES
The MA of a wheel and axle can be calculated by the ratio of the radius of the wheel to the radius of the axle. If an axle has a radius of 2 in and the wheel has a radius of 6 in what is the MA of the?

A Ferris wheel has radius 50 ft A person takes a seat and the wheel turns 2pi over 3 how far is the person from the ground?
He is 75 feet high.
What is the IMA of a wheel and axle?
The IMA of a wheel and axle is the radius of wheel divided by the radius of the axle.
When does a wheel and axle have a mechanical advantage greater than one?
