Physics 2010 JAMB Past Questions - Question 9: The surface of conveyor belts are made rough so as to

Correct Answer

A

Explanation

The surface of conveyor belts is often made rough for several reasons:

1. Improved Traction: The rough surface provides better traction for the materials being conveyed. This is particularly important when moving heavy or bulky items, as it helps prevent slippage and ensures that the materials are transported more efficiently and safely.

2. Reduced Material Slippage: The rough surface helps prevent materials from sliding or falling off the conveyor belt. This is especially crucial in industries where product integrity and safety are paramount, such as food processing and manufacturing.

3. Enhanced Grip for Incline Conveyors: For conveyor systems that operate on inclines or declines, a rough surface is vital to ensure that items can be moved up or down without the risk of sliding back.

4. Better Control: The rough texture of the conveyor belt can provide better control over the speed and movement of materials, helping to avoid sudden jerks or stops, which can be damaging or disruptive to the production process.

5. Compatibility with Specific Materials: In some industries, the rough surface of conveyor belts is designed to be compatible with the specific materials they handle. For example, certain abrasive or granular materials may require a rough surface to prevent excessive wear and tear.

6. Efficient Sorting and Separation: In sorting and separation applications, the rough surface can be used to create friction between items, making it easier to separate and divert materials as needed.

The type of conveyor belt surface chosen will depend on the specific needs of the industry and the materials being transported. Smooth and rough surfaces are both used, but a rough surface is selected when additional grip and control are required for the conveyed items.
