The simple machine called a wheel and axle refers to the assembly formed by two disks, or cylinders, of different diameters mounted so they rotate together around the same axis. The thin rod which needs to be turned is called the axle and the wider object fixed to the axle, on which we apply force is called the wheel.

As in a wheel barrow, the axle of the wheel is the fulcrum, the handles represent the position where the effort is applied, and the load is placed between the hands and the axle.

A wheel with a rod, called an axle, through its center lifts or moves loads. Pulley is a simple machine that uses grooved wheels and a rope to raise, lower or move a load. An inclined plane is a slanting surface connecting a lower level to a higher level.

If the fulcrum is closer to the load, then less effort is needed to move the load. If the fulcrum is closer to the effort, then the load will move a greater distance.

The wheel and axle consists of a round disk, known as a wheel, with a rod through the centre of it, known as the axle. This system uses angular momentum and torque to do work on objects, typically against the force of gravity. The wheel and axle simple machine is closely related to gears.

Wheel and Axle: A crank-type pencil sharpener employs a wheel and axle in addition to a wedge; you turn the axle by turning a crank, which then transfers the force from your hand to the wheel. Other examples of a wheel and axle are bicycle gears and steering wheels.

Wheel and axle uses include lifting heavy objects, moving people quickly, and moving parts of a complex machine.

The object with the larger radius is called the wheel and the object with the smaller radius is called the axle. In a screwdriver, the handle is the wheel and the shaft is the axle. A doorknob and a car’s steering wheel are also examples of a wheel and axle.

Answer: A windmill. Explanation: A mechanical device which consist a grooved wheel which is turned by the chord or chain which is attached through axle with a supporting standard.

Shifting friction to the axle There must be friction between the four wheels and the ground or they’d simply slide along (like something being pushed on ice). Friction between each wheel and the ground helps it “dig in” so the wheel can rotate.

Wheel bearings have an average lifespan of 136,000 to 160,000 km (approximately 85,000 to 100,000 miles). This is only a rule of thumb though, the actual lifespan of a wheel bearing depends on the quality of the wheel bearing and the operating conditions.

Bad Wheel Bearings. If you just bounce the right front tire of a pickup truck over the curb every time you do a U-turn, that wheel bearing is much more likely to go bad. If this is the issue, you may notice a shaky steering wheel and the shaking may continue through the rest of the vehicle.

How much does an alignment cost? A front-end alignment usually costs between $65 and $100 (some brands, of course, are more). At that price, it should be a regular part of your car care regime. To make an alignment even more economical, some car care facilities offer lifetime alignment packages for around $200.

How To Check Wheel Alignment At Home

1. To check the toe, park the vehicle on level ground with the tires straight ahead and the steering wheel centered.
2. Measure from line to line with the tape level with the floor.
3. Measure again on the back sides of the tires.
4. If the steering wheel is already centered, adjust the tie-rods on each side the same amount.

RAY: But centering the steering wheel is something that should be done as part of a front-end alignment. TOM: Having the steering wheel “agree” with the direction of the wheels isn’t a mechanical necessity. Your car will steer fine regardless. Then you align the front wheels so that they’re pointing straight ahead.
