Question: 1 / 400

What is the consequence of having too little tension in a mechanical belt system?

Increased power transmission efficiency

Reduced risk of belt slippage

Improved operational speed

Increased likelihood of slipping

Having too little tension in a mechanical belt system leads to an increased likelihood of slipping. Proper tension is essential for maintaining grip between the belt and the pulleys it connects. When the tension is insufficient, the friction required to transfer power between the belt and the pulleys decreases, causing the belt to slip. Slipping not only diminishes the effectiveness of power transfer, but it can also lead to wear on the belt and pulleys over time, potentially resulting in mechanical failure or the need for replacement.

In contrast, increased power transmission efficiency, reduced risk of slip, and improved operational speed are benefits associated with an adequately tensioned belt system. Thus, maintaining proper tension is crucial for effective operation in mechanical systems utilizing belts.
