Consider the following statements A) The coefficient of friction between two surfaces will increase if the surfaces are made rough. B) rolling friction is more than sliding friction
What happens to the coefficient of friction if the weight of the body is doubled ?
An engine of one metric ton is going up an inclined plane, 1 in 2 at the rate of 36 kmph. If the coefficient of friction is 1//sqrt(3) , the power of engine is
