Throughout history, humans have developed several simple machines to make work easier. The most notable of these are known as the "six simple machines": the wheel and axle, the lever, the inclined ...

People have long assumed that wheels evolved from simple wooden rollers. But how? And why? A new model focused on mechanical advantage and structural strength suggests some answers.

What is a wheel and axle mechanism? A wheel and axle mechanism is a simple device you make when you connect one or more wheels to an axle. They are used to help things move. A wheel is a round ...

Find out how simple machines makes work easier on this Science Trek. Simple machines include the lever, the inclined plane, the wedge, the pulley, the wheel and axle, and the screw. Combine these ...

It's possible that the wheel was invented by copper miners in the Carpathian Mountains up to 6,000 years ago, according to a modeling study that uses techniques from structural mechanics.

These models feature the Dynamic Performance Control system, an upgraded version of xDrive that can distribute torque between axles and the two wheels on the rear axle.

Or, if customers prefer, the drive axle can be used in place of the transfer case. The all-wheel drive Model 567 is now available for order and will go into production in April.
