Study Notes

Mechanical Advantage and Inclined Planes

The mechanical advantage of an inclined plane is the ratio of the effort applied to the weight lifted.
Moving an object up an inclined plane requires less force than lifting it straight up because the force applied is distributed over a longer distance.
The angle of friction is sometimes called the angle of repose.

Friction and Inclined Planes

The maximum angle at which a load can rest motionless on an inclined plane due to friction without sliding down is called the angle of repose.

Inclined Planes in Practice

Inclined planes are used to move heavy loads over vertical obstacles, making it easier to lift heavy objects.

Metrology and Units of Measurement

The International Bureau of Weights and Measures (BIPM) is tasked with ensuring worldwide uniformity in measurements.
Metrology is the science of measurement.
The International System of Units (SI) is the modern metric system used globally.
Units of measurement in physics and metrology serve to provide a common language and standard for expressing physical quantities.
The International Bureau of Weights and Measures (BIPM) plays a crucial role in facilitating international trade by ensuring that measurements are consistent and reliable.
