Why is it easier to turn a knob instead of its axle?
Because of the torque multiplication of the knob, making it easier to turn the shaft,
Compare a wheel and axle to a lever?
The wheel and axle is a simple machine. It is consists of a wheel that turns an axle and in turn a rope converts the rotational motion to linear motion for the purpose of lifting.
How is wind energy turned into electricity?
A pinwheel, fan, or other spinning device, attached to the axle of an electric generator, is stuck up into the wind. As the wind spins the device, the device in turn spins the generator.
How can the energy from moving water be used to produce electricity?
Water can turn a wheel, which turns an axle connected to an electrical generator which generates electricity by moving magnets so that their magnetic fields pass through wires.
Why does the transfer of thermal energy through conduction happens more quickly in a solid than it does in a gas?
Liqiud water can turn to ice faster than it can turn to gas. It can boil faster than it can freeze though.
Is doorknob a wheel and axle?
Yes, a doorknob is considered a wheel and axle because when you turn the doorknob to open the door you are turning it so you can open the door.
What part of a doorknob is the wheel?
The large part you grab and turn is the wheel. The rod down the center would be the axle.
Why is it easier to turn a knob instead of its axle?
Because of the torque multiplication of the knob, making it easier to turn the shaft,
When the axle invented?
The axle helped in many ways and it was one of the most important inventions. The axle came along with the wheel.The wheel and axle were both one if the most important inventions. The wheel and axle help to transport fod from place to place. They were usually pulled my horses and/or oxen. The axle made it easier to turn corners and the wheel made it easier to transport items. The wheel and axle were invented my the Egyptians at about 3,500 B.C. Hope this helped whoever need an answer to this question! <3
Why is it important that the diameter of the wheel be greater than the diameter of the axle in a wheel and axle?
because the wheel turns through a much greater distance than the axle.but the smaller turn of the axle is more powerful.witten by-brenda v.=========================Answer #2:-- The fact that the wheel turns through a greater distance that the axle doesis a result, not a cause, of the wheel being bigger than the axle.-- The axle is not more powerful than the wheel. Ignoring losses, they must bothhave the same power. The axle's force is greater than the wheel's force, but to payfor it, the axle must turn through greater distance. Same as all the lever stuff.-- The diameter of the wheel needs to be greater than the diameter of the axleonly if you'd prefer not to have the axle scrape on the ground.
What makes tires turn?
the axle or trans-axle
What do wheels turn on?
an axle
What is the function of the differential unit of a car?
It allows the two axle shafts in the axle to rotate at different speeds, e.g., such as when the car is making a turn, the outer axle shaft will need to rotate faster than the inner.
What does the wheel turn on a wheel and an axle?
The wheel generally turns the axle.
Why will decreasing the radius of the axle improve the mechanical advantage of a wheel and axle?
it's a mechanical advantage of 1 (meaning no mechanical advantage). This is because no matter how much easier it is to spin a the wheel rather than the axle, its a longer distance of effort force and vice versa. * * * * * True, but that is not what mechanical advantage is! Mechanical advantage IS the trade off between the force required and the distance travelled. You can find the ideal mechanical advantage of a wheel and axle by dividing the radius of the wheel by the radius of the axle. * * * * * Better. But I think it could be either of the two reciprocal ratios of the radii, depending on whether the wheel/axle is being used in a 2nd class or 3rd class lever configuration ... i.e., are you cranking the wheel in order to turn the axle, as in a winch, or spinning the axle in order to turn the wheel, as in a motor-vehicle ?
Is a doorknob a screw?
Yes, it is! When you turn it, it goes inward (I think...) so after you can go inside the room you wish to be in.
What part does a wheel turn on?
The wheel turns on an axle.
