FAQs on Examples on Dry Friction - Engineering Mechanics - Civil Engineering (CE)

1. What is dry friction?
Ans. Dry friction refers to the resistance to motion between two solid surfaces in contact with each other, where no lubricant or fluid is present. It occurs due to the interlocking of microscopic irregularities on the surfaces, which results in a force that opposes the relative motion.
2. What are the factors influencing dry friction?
Ans. Several factors influence dry friction, including the nature of the materials in contact, the roughness of the surfaces, the normal force pressing the surfaces together, and the temperature of the environment. These factors determine the magnitude of the frictional force.
3. How is the coefficient of friction related to dry friction?
Ans. The coefficient of friction is a dimensionless quantity that represents the ratio of the frictional force between two surfaces to the normal force pressing them together. It is a measure of the intensity of dry friction and depends on the properties of the materials in contact.
4. Can dry friction be advantageous in certain situations?
Ans. Yes, dry friction can be advantageous in certain situations. For example, it allows us to walk or drive vehicles by providing the necessary grip between our feet or tires and the ground. Additionally, dry friction is utilized in brakes, clutches, and other mechanical systems to control and stop motion.
5. How can dry friction be reduced or eliminated?
Ans. Dry friction can be reduced or eliminated by introducing a lubricant or fluid between the surfaces in contact. The lubricant forms a thin film that separates the surfaces, reducing the interlocking and allowing them to slide more easily. This reduces the frictional force and minimizes wear and heat generation.
