How does the mechanical advantage of a wheel and axle changes as the size of the wheels increase?
The velocity factor of a wheel depends on its diameter. If we take the velocity factor as a measure of how far the vehicle moves in one revolution of the wheel, then it is equal to the circumference of the wheel, which is pi times the diameter.

How you would measure the mechanical advantage of a bicycle?
To measure the mechanical advantage of a bicycle, you would compare the input force applied by the rider to the output force produced at the wheels. The mechanical advantage is calculated by dividing the output force by the input force. In the case of a bicycle, the mechanical advantage helps determine how efficiently the rider's pedaling translates into forward motion.
How the mechanical advantage of a wheel and axel change as the size of the wheel increases?
As the size of the wheel increases, the mechanical advantage of the wheel and axle system also increases. This is because a larger wheel allows for a larger distance to be covered with each rotation, resulting in less force required to achieve the same work. Therefore, larger wheels provide a greater mechanical advantage compared to smaller wheels.
When is it useful for some tasks to have a mechanical advantage less than 1?
The mechanical advantage is less than 1 when the output is less than the input. Mechanical advantage is expressed as the ratio of the output to the input. You can move an object far faster than your source of power is capable of working. Such as in the final gears in your car, where the wheels are turning faster than the engine is.
What is the advantage of a pulley?
Of a single pulley wheel, only that it changes the direction of the force ie: from overhead. > On a block and tackle system, 2 or more pulley wheels are used in a certain way to produce mechanical advantage. The simplest type of block and tackle offers a mechanical advantage of 2
What type of simple machine is it?
A simple machine is a mechanical device that changes the direction or magnitude of a force. Examples include levers, pulleys, inclined planes, wedges, screws, and wheels and axles.
What are the advantages of using small pulley wheels in a mechanical system?
Using small pulley wheels in a mechanical system can provide advantages such as increased mechanical advantage, reduced friction, and the ability to fit into tight spaces.

What factors determine the mechanical advantage of pulley system?
Disregarding friction and other losses, mechanical advantage N = F/f which is force into the system f and force out F. We can think of each wheel in a pulley system as being part of a lever. And each lever has its own mechanical advantage n = F/f = L/l where L is the long end from the fulcrum and l is the short end from it. And there we are. Those lengths, L and l, have their analogs in the pulley wheel radii or diameters (they are equivalent). So if you have a pulley system made up of two connected wheels, with diameters D and d, the mechanical advantage of the system is N = D/d or R/r for radii. If there are more than two wheels, we can simply multiply the mechanical advantages between each pair of connected wheels to get the total mechanical advantage of the entire system.

Is belts and wheels mechanical parts that transmit forces?
no
What is the trade off between mechanical advantage and the distance within pulley systems?
The trade-off between mechanical advantage and distance in pulley systems is based on the principle of work. Increasing the mechanical advantage by adding more pulleys decreases the amount of force required to lift an object but also increases the distance the rope needs to be pulled. This is because the work input (force x distance) remains constant, so as force decreases, distance must increase to maintain the same amount of work.
What are the advantages of a mechanical advantage that is less than 1?
You can move an object far faster than your source of power is capable of working. Such as in the final gears in your car, where the wheels are turning faster than the engine is.
How many wheels does a eggbeater have?
A simple eggbeater such as a fork or whisk has no wheels, a simple mechanical whisk would have two wheels and an electrical whisk may have several wheels.
What is A sentence using mechanical energy in it?
The moving car has mechanical energy as its wheels turn and propel it forward.
What type of simple machine is it?
A simple machine is a mechanical device that changes the direction or magnitude of a force. Examples include levers, pulleys, inclined planes, wedges, screws, and wheels and axles.
