What are the ways to decrease the friction force? Cars work! When equipment and systems rotate while under operation, radial and axial loads are produced which may begin to cause damage if left unchecked. Different Methods Of Reducing Friction. They slip when the torque exceeds a safe value, thus safeguards the machine. Disadvantages of friction: 1. Just 5 advantages and disadvantages of "Friction" SOS, please, help me!!!! 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. Join now. There are advantages and disadvantages of friction. 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!!!! 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. 3. Without friction we are handicap.1. its disadvantage is:-components of machines are worn due to heat produced due to friction between machines. We can not fix nail in the wood or wall if there is no friction. Advantages of friction clutch. 3 . However, there are both advantages and disadvantages of friction, and that is exactly what we are going to talk about today. Brake works on the basis of friction. 4 Answers. Friction is the force that arises from the contact of two bodies and prevents their relative movement. Find out for yourself why friction is good and bad at the same time. In those cases, there is an advantage of having friction. They are capable of transmitting partial power. Ask your question. The transfer of motion from one part of a machine to other part through belts is possible by friction. Small working stroke and short opening and closing time. The biggest disadvantage of friction is wear and tear that happens as a result of friction.
