Explain, using examples, the different market entry strategies, including the advantages and disadvantages of each. The disadvantage of the friction. Used when speed difference between the shafts is low ; They cannot be used at high speeds because it may result in a shock; Friction clutches. 1. explain the advantages and disadvantages of friction. Explain with four examples that sometimes, force of friction is desirable. Pros: friction provides a resistive force to the motion of objects. The heat induced by friction makes the parts that need to be joined together more malleable. Here are some examples of static friction : A heavy box against the ground, difficult to lift and move. A dry and a wet plastic, where the second has less friction than the first. examples of forces are kicking a football, lifting a table. Last, but definitely not least, friction is the reason we have discovered how to create fire. Question 10 How friction reduces the efficiency of machines? Friction plays a vital role in our daily life. Extra friction makes it difficult to move an object, such as sliding a box across the floor or walking in deep snow. Answer: Advantages: a) Friction makes it easy to walk. ← Prev Question Next Question → 0 votes . If you contemplate across this question then you will answer “nothing” Obviously if we compare advantage and disadvantages of friction then we will clearly say that thare are neither any friction lose nor disadvantages. The section on Theory of Machines - Mechanisms includes a section on Friction both on flat surfaces and in Bearings. Remember. Question 6 Explain why soles of shoes wear out gradually? Therefore friction would be proportional to the area of contact, and therefore proportional to the normal pressure, as assumed in the above laws. When we move on ice, it becomes difficult to walk due to low friction of ice. Examples of static friction. Walking. Explain why sportsman use shoes with spikes. We can not fix nail in the wood or wall if there is no friction. It is becomes difficult to walk on a slippery road due to low friction. The ball is acted by an external force and it stops. Q57. For example when a racing car needs to go fast the friction against the air will end up slowing down the car which is of course useless because a race is all about who can go faster :). Without friction between the shoes and the ground, you cannot walk properly. When there is a lot of friction between moving parts, energy is lost to the surroundings as heat. We also sometimes rub the surface with a fine sand paper to reduce their unevenness. Explain with 3 examples the disadvantages of friction Ask for details ; Follow Report by Klavanya1109 05.09.2018 Log in to add a comment Fluid friction is defined as the friction that exists between the layers of the fluid when they are moving relative to each other. 2. disadvantages are that it requires more effort to get work done, and there is heat, and friction may also cause wear and tear. Disadvantages: a) Wear and tear of the tyres b) It opposes the smooth motion of the objects. We can write with pencil or pen on the paper on the board using friction. The friction warms them up. The surface becomes smooth and friction gets reduced. The view container be used to hide approxima view the full answer Methods of reducing friction are : 1. Physics for Class XI, Explained Force of friction with examples. A nightstand resting on a light table. Share 3. the disadvantages of friction are: 1.when 2 surfaces rub with each other heat is generated.this can be useful as well as disadvantage.for example,say a tailor is stitching clothes. When we walk on the road … Explain with examples the disadvantages of Friction.In about 60 words fast Share with your friends. Login. This external force is referred to as friction. What are the ways to decrease the friction force? Question 11 How friction damages the machine parts? The disadvantages of friction are as follows. If a company has a debt ratio of 50.1%, they are financing assets primarily with debt. Some of the Advantages of Friction are: We can walk with the help of friction between our shoes and the ground. Liquids and gases are included in fluids. Share with your friends. advantages of friction is that you can walk without slipping everywhere and you can write on your paper. Large downward forces are required to get the probe tool get inserted inside the metal. Without friction we are handicap. Your bike will be noisy and difficult to pedal. Examples of Friction. This question has not been answered yet! Kindly refer the link for similar query. When friction slows you down the energy is converted into heat energy, it is bad in some cases. Following are the examples of fluid friction: The flow of ink in pens; Swimming; Stay tuned with BYJU’S to learn more about other concepts of Physics with interactive videos. It is commonly a type of friction welding but due to its versatile applications, it is considered as a separate welding process. In friction clutches engagement between the shaft happens due to friction between them. The advantages of frictional force are immense, think upon the activities that indulge in daily life. Examples of SLIDING FRICTION is pushing a heavy rock in your path, or moving a box on the floor. For example, a bicycle will eventually stop if it not cycled consistently. So friction helps to keep objects stationary. What is examples of friction? NOTE. Disadvantage: - Sometimes it can be a waste of energy. 5 views. Limitations / Disadvantages: The hole which is made by the blunt probe tool is left unfilled at the time of exit. fayizarahimeen18 is waiting for your help.
