ADVANTAGES OF FRICTION Friction plays a vital role in our daily life. 3. When equipment and systems rotate while under operation, radial and axial loads are produced which may begin to cause damage if left unchecked. So imagine if everything were completely slippery. Today we will learn about friction welding principle, working, types, application, advantages and disadvantages with its diagram. However, too much friction can be a nuisance, because it can hinder motion and cause the need for expending extra energy. Answer Save. Friction produces heat. This heat makes the metal plastically melt. Advantages of friction: 1. It is becomes difficult to walk on a slippery road due to low friction. Without friction we are handicap.1.

Good sealing performance, small friction between sealing surfaces and long life. Advantages and Disadvantages of Antifriction Bearings. Question 8 State few disadvantages of friction? Like walking or driving or holding things. Friction is good for us as well as dangerous and disadvantages having it. Log in. Since friction is a resistance force that slows down or prevents motion, it is necessary in many applications to prevent slipping or sliding. ADVANTAGES 1) Helps us walk, we wud slip if not for friction 2) Helps us hold on to things 3) Tecnically, helps running of rope and belt drives 4) Helps absorb kinetic energy (As in braking a car) 5) Helps in intermittent power transmission, when required (clutch) DISADVANTAGES 1) Produces heat 2) Reduces mechanical efficiency of ALL MACHINES!!!! Writing is not possible without friction. The disadvantage of the friction. Advantages and disadvantages of friction welding Friction welding works on the basic principle of friction is used to generate heat at the interference surface this heat is used to join two workpieces by applying external pressure at the surface of the workpiece. 2. (Advantages of Friction)Or we can also say, what are the different uses of FrictionFriction is used to-Help us walk without slippingFriction helps in walking on the ground because friction between o 1. Question 9 Why brake pads wear out gradually? Wear is the gradual removal of material at solid surfaces occurring as a result of damage caused by friction and/or corrosion. When we move on ice, it becomes difficult to walk due to low friction of ice. Answer (1 of 10): Advantages of friction1. Friction plays a vital role in our daily lives. The reason a car’s wheels propel the vehicle in a forward motion is because of the force of static friction acting between the lower edge of the wheel and the road. There are advantages and disadvantages of friction. These are a few of the great many advantages and disadvantages of having friction in sport: Friction allows a running person to stop, change direction, jump, catch a ball, and throw a ball. One such example is- The friction between the sole of a shoe and the surface of the ground prevents us from slipping, it helps the drivers to control the speed of the vehicle and friction can also be used to start fires. 2. 4 Answers. Without it, nothing could have been possible. Friction enables us to walk freely. Advantages. Two body sticks together due to friction. Bearings are machine elements, implemented within an assembly to limit motion to a specific movement and to mitigate friction between moving components. Friction welding is a solid state welding process. 1)Friction wears away the soles of our shoes. Anonymous. Take walking, for example, one finds it extremely difficult to walk on a slippery road for it lacks friction. It is becomes difficult to walk on a slippery road due to low friction. That would be bad for most things in real life. In this way some useful energy is wasted as heat energy. Join now. Favorite Answer. A main disadvantage of friction is that it causes energy in a system to be converted to heat or sound energy, making that system less efficient. What is friction? Advantage Disadvantage Bycicle brake keep on going car brake keep on going Is a pipe gripped by a stillson wrench an advantage or disadvantage of friction? Easy to operate. its disadvantage is:-components of machines are worn due to heat produced due to friction between machines. It’s tempting to think of this as dynamic friction, but not so. Click here to get an answer to your question ️ How is the heat produced by friction both an advantage and a disadvantage? Friction helps us to write on notebooks and boards. Since friction is a resistance force that slows down or prevents motion, it is necessary in many applications to prevent slipping or sliding. Solid state welding are those welding process in which no external heat is applied or no molten or plastic state involves. In your daily life friction plays an important role and those are as follows:-Without friction, it is not possible to hold and handle any substance. ADVANTAGES OF FRICTION Friction plays a vital role in our daily life. 1 decade ago. 2 . The biggest disadvantage of friction is wear and tear that happens as a result of friction. Concept Of Lubrication, Advantages, Disadvantages Concept Of Lubrication, Advantages, Disadvantages This question hasn't been answered yet Different Methods Of Reducing Friction. Also Read: Friction Welding Process – Working, Types, Advantages, Disadvantages with Application 3 . Relevance. Friction Welding (FRW) is a solid state welding process which produces welds due to the compressive force contact of work pieces which are either rotating or moving relative to one another. For a similar reason, crutches are provided with rubber tips at their bottom to provide sufficient friction.2. Small working stroke and short opening and closing time. But also, it can be a nuisance because it can hinder motion and cause the need for expending energy. When the metal gets plasticized the high downward forces or pressure makes a strong, clean and solid-state weld. In this video, we will learn all the advantages and disadvantages of friction. In those cases, there is an advantage of having friction. At the end of this Topic, Student should be able to: Explain friction; Mention the application of friction; State the advantages and disadvantages of friction; Explain ways that frictional force can be reduces; TEACHING AND LEARNING MATERIALS. Advantages of friction. Due to contact of the workpiece, friction is applied and as a result of it, heat is generated. Just 5 advantages and disadvantages of "Friction" SOS, please, help me!!!! Heat is produced due to the friction which displaces material plastically from the faying surfaces. The advantages of frictional force are immense, think upon the activities that indulge in daily life. 1. Question 10 How friction reduces the efficiency of machines? Brake works on the basis of friction. Advantages and Disadvantages of Frictional Force. 1)Friction enables us to walk without slipping. Any machine with moving parts is subject to the deleterious effects of friction and wear. Ask your question. Cars work! Wear leads to loss of functionality. It helps to support ladder against wall. # 9th Class Physics # Ch 3 DynamicsAdvantages and disadvantages of Friction. In slippery surfaces, friction helps you to hold and walk. It is friction which holds the nail. The breakers and tiers of our cars and bicycles depend on friction to function properly.3.
