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 ?

The simple application is the turning of the tool in a hole will create a thread for a bolt to travel in.

The most simplest could be a drill press or band saw

Personally, I call it the "pivot", but it's more properly

and elegantly referred to as the " fulcrum".

The can opener was invented after the invention of the can. Before it's arrival, cans were opened by many and dangerous ways. The dedicated opener made the operation quicker and safer than previous methods.

Friction force oppose motion between two bodies that are in contact. This force is important in machines and pulley systems in that it enables the gears to have grip and there is no unnecessary sliding.

Instantaneous power doesn't have a frequency; it's instantaneous!

ENDING OPERATIONS AND CLEANING UP Ensure the handle is left in a safe position after use. Leave the work area in a safe, clean and tidy state. POTENTIAL HAZARDS AND INJURIES Sharp edges and burrs. Crush and pinch points. Hair/clothing getting caught in moving machine parts. Operator’s hands may be caught and drawn into the counter-rotating rollers.

A light bulb is a simple machine. A light bulb is a screw.A screw is a simple machine.

A wheelbarrow is a complex machine: it incorporates a wheel and the handles form a lever. (That's not considering details like screws to hold it together--primitive wheelbarrows didn't have screws).

The door on hinges would be a lever and the door knob would be a wheel and axle.

There are gears in the motor and engine. The tires are connected to a wheel and axle, so is the steering wheel. The actual forklift acts as a lever. The tips of the fork are actually wedges, but that is irrelavent.

Screw Pitch is defined as the axial distance between threads. One complete revolution of the screw will move it into an object the distance of the pitch. The smaller the pitch, the greater the mechanical advantage (ability to do work) achieved.
