Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

- Indicates impending motion with an arrow, showing the direction of movement.
- Labels \( T_2 \) and \( T_1 \) represent the tensions in the belt on either side of the pulley.
- The angle \(\beta\) is shown as the angle subtended by the belt on the pulley, centered at the pivot.

- **Right Diagram:**
- Provides a cross-sectional view of the V-belt.
- Shows the angle \(\alpha\) as the angle of contact between the belt and the pulley sides.

This relationship is fundamental in understanding the mechanics of belt drives and their efficiency in transmitting power.
