Friction stir welding (FSW) is a solid state welding process. advantages of friction is that you can walk without slipping everywhere and you can write on your paper. However, it is not always a good thing. Friction makes wear and tear of the machinery Extra energy is required to move the heavy body or vehicle or automobile. As we have mentioned before, friction produces heat. For example, a bicycle will eventually stop if it not cycled consistently. Even though the fact that friction slows things down can often save our lives, it can also seriously hamper everything. Friction opposes motion and the tendency to move. Assign to Class. • Login. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. The friction between two surfaces is necessary and it results in the resisting of force between the two surfaces. Friction is a force between two surfaces that are sliding, or trying to slide, across each other. What are the ways to decrease the friction force? • This could overheat and damage them. In this way, useful energy is expended as a loss in thermal energy. 1. Ask your question. https://www.meritnation.com/ask-answer/question/advantages-and-disadvantages-of-friction/science/9564491 Friction is the force that opposes motion between any surfaces that are in contact. Another way to prevent getting this page in the future is to use Privacy Pass. Some of the Disadvantages of Friction are: Sometimes friction produces heat in the machinery or its parts. Wear is the gradual removal of material at solid surfaces occurring as a result of damage caused by friction and/or corrosion. Why friction is evil? We can’t keep chain drive-in open.
