If the motor makes 400 revolutions every minute how fast does the wheel rotate in RPM?

That depends on the relative sizes of the gear shafts used to transmit power from the motor to the wheel. For instance, if they were the same size, and no gears in between, then the wheel would rotate 400 times a minute (RPM), which is 6.66 times a second. But usually gears transmit power in such a way that the wheel rotates slower than the motor (less RPM) but with more power.

How many circles does a minute hand make in a day?
The Minute hand makes a full circle of the clock's dial every Hour. Since there are 24 hours in a day, then the Minute hand travels 24 full circles every day.
How many revulsions does a tire 275 80R22.5 make in one minute?
It is unknown how many revolutions a 275/80R 22/ 22.5 tire makes in one minute. It all depends on who is driving and how far they go. This answer is wrong! If this tire is going say 60 mph their must be some mathematical way to figure this question out
What is a minute hand on a clock?
The minute hand is the largest hand on most analogue clocks. At 3 o'clock on a 12-hour clock, the minute hand is pointing straight up to the 12. It measures time to the nearest minute by advancing one of the small minute hash marks every 60 seconds. Every time the second hand makes one full sweep of the clock face, the minute hand advances one of the minute marks. The second hand is the fastest moving hand on a standard analogue clock, making one full sweep every 60 seconds.
How many degrees does the minute hand move in 15 minutes?
It moves 90 degrees because it forms a right angle with its previous position.
What are all numbers than make a square?
All numbers can make a square. Every real number makes a positive real square. Every rational number makes a rational square. Every integer makes a perfect square.
How many revolutions minute hand makes in one hour?
60
What does car speed at 1000rpm means?
Revolutions per minute is the # of times an engine makes a complete 360 revolution in one minute.
What is RPM meter in a car?
Revs per minute- the amount of revolutions the engine makes in 1 minute Generally called a tachometer.
The camshaft makes how many revolutions for a full revolution of the crankshaft?
it's a 2 to 1 ratio For ALL 4 cycle engines, no matter how many cylinders, the crankshaft turns twice for every turn of the camshaft.
How many revolutions per hour does the minute hand move on big ben clock?
The minute hand of any analog clock moves 1 revolution per hour. (60 minutes to an hour) The second hand makes 60 revolutions an hour. (Each tick represents one second, one revolution per minute, equals 60 revolutions an hour.)
What speed Hdd is measured at?
RPM = revolutions per minute - or - how many times the discs makes a complete spin around its center (axis) in a minute, just like a fan does.
What is the speed of an steam engine?
It is the number of strokes (forward and back) the piston makes in one minute. For radial (turbine) and rotary steam engines, it is the number of revolutions per minute.
How many revolutions does the crankshaft make per second at 3000 rpm?
(3,000/minute) x (minute/60 seconds) = 50/second
What is low range power in motor vehicles?
Low range power is the power your motor makes in the low range of rpms( revolutions per minute).
A wheel on a vehicle has a diameter of 36 inches If the vehicle is moving at a speed of 50 mph how many full revolutions will the wheel make in one minute?
1760 yards = 1 mile. 60 minutes = 1 hour. 36 inches = 1 yard. 50*1760 divided by 60 = 1466 yards 2 feet in one minute Circumference of wheel = pi*36 = 113.0973355 inches 113.0973355/36 = 3.141592654 yards 1466.666666/3.14192654 = 466.8048878 revolutions in one minute So the wheel makes 466 full revolutions in one minute.
What is the meaning of drill speed?
Drill speeds are almost always measured in revolutions per minute, RPM or revolutions per second, RPS. This term means that the drill makes a complete revolution that many times in the specified time period. 7200 RPM means that it will revolve 7200 times in a minute, or 120 times in a second. Some materials require specific drill speeds in order not to damage them. The limits are usually on the maximum speed.
The short hand and long hand clock are 4cmand6cm long respectively find the distance traveled by their tips in two days?
Every day, the hour hand makes 2 complete revolutions and the minute hand makes 24 revolutions (one per hour). So we have 4 complete revolutions on the hour hand and 48 on the minute hand. First, let us find out the distance per revolution these make. If you noticed on a clock, these would be considered radii, the minute hand makes: C = 2πr ==> C = 2π(4) ==> C = 8π ==> C ≈ 25.133 cm/revolution and the hour hand makes: C = 2πr ==> C = 2π(6) ==> C = 12π ==> C ≈ 37.699 cm/revolution So the sums are: 48(8π cm) + 4(12π cm) = 384π cm + 48π cm = 432π cm ≈ 1,357.168 cm Therefore, the sum of the distances traveled is about 1,357 cm.
