Wheel and belt systems are designed to provide a mechanical advantage and increase the effectiveness of torque. This is achieved through the use of belts that connect wheels, allowing for the transfer of rotational motion and torque from one wheel to another. When the driving wheel turns, it pulls on the belt, which in turn rotates the driven wheel. This setup allows for the multiplication of force—meaning that a small input force can result in a larger output force, enhancing the overall system's efficiency and torque capability.

The first choice is not accurate because wheel and belt systems primarily facilitate the transfer of motion rather than specifically converting linear motion to angular motion. The second choice is misleading since these systems rely on tension and the interaction of surfaces rather than power input primarily from friction. The fourth choice is incorrect because wheel and belt systems can operate at variable speeds, not just constant speeds.

Thus, the option that highlights the ability of wheel and belt systems to increase torque effectiveness aligns with the fundamental purpose of these mechanical systems.
