Banking of car |
|
Answer» Banking of roads means to construct a road in such a way so that its outter side lift in little bit upward direction. This is done to prevent accidents because on a levelled road if the speed increase from [urg]1/2 then the friction is unsufficent to provide centripital force and the car will skid off Thanks? On a levelled road basically depends upon the coefficient of static friction but friction is not reliable as it changed as the change in the condition of tyre and road and other climatic condition so to add safety a curve is constricted with its outer edges are little raised above the inner edge and is called banking of curve |

what is hooks law ? |
|
Answer» If strain is very small then the ratio of stress to strain it is known as hook\'s law Hooke\'s LawWithin the elastic limit of a solid material, the deformation (strain) produced by a force (stress) of any kind is proportional to the force. If the elastic limit is not exceeded, the material returns to it original shape and size after the force is removed, other it remains deformed or stretched. The force at which the material exceeds its elastic limit is called \'limit of proportionality.\' Discovered in 1676 by the UK scientist and inventor Robert Hooke (1635-1703). See also elastic modulus. |

What is second law of thermodynamics ? |
|
Answer» second law of thermodynamics us stated by two persons :-1. Kelvin plank 2. Claussius...1. kelvin stated that it is impossible to create a engine which absorbs heat energy from the source and turns completely into work without rejecting any part to the sink...2.claussius stated that it is impossible to create a self acting machine without any external source which would transfer heat energy from a body of high temperature to the body of low temperature. It is impossible for an heat engine to have 100 percent efficiency |
