Latest Answer: There are laws of thermodynamics1. Zeroth law2. First law of thermodynamics3. Second law of thermodynamics4. Third law of thermodynamicsZeroth laws says that energy can neither create nor be destroyed. It can be transform from one form into another.First ...
What are Barriers and Tunneling?
Why do most of the vehicle have disc brake only in the front axle?
Latest Answer: While applying brake, the momentum of the vehicle will be transferred to front portion so it is necessary to have more braking force on front axle, that is why disc brake is used in front axle. ...
Why the thermal efficiency of the engine decreases at part load?
Latest Answer: There are always some mechanical losses in the engine while running. These losses are more or less same at all the speeds. When the speed decreases, the output will obviously decreases. But, the losses remain same. So, the overall efficiency also decrease. ...
How to find the max load of the engine?
Latest Answer: By using dynamometers. ...
What is the practical difference Speed and Torque?
Latest Answer: speed is the distance traversed per unit time.. it is a scalar quantity. torque is the vector product of distance and force..it is a vector quantity. torque= r * F where r is distance between point of application of force and the point about which torque ...
What is the difference between reversible process and cyclic process in thermodynamics?
Latest Answer: Reversible process is one in which the system and surroundings can be restored to their initial states by reversing the process.eg. in thermodynamics, A(P1,T1) B(P2,T2) is a reversible process.Cyclic Process is one in which the initial and ...
What happen if we pour petrol in diesel engine and vice versa? Explain
Latest Answer: When petrol is used in diesel engine, the engine will not work as gasoline (petrol) has high ignition temperature and therefore has to be ignited by spark-ignition. Diesel engine on the other hand works on the principal of self-ignition in compressed ...
Which is more elastic - Steel or Rubber?
Latest Answer: Elasticity is the capability of an object to return to its former shape once a load inducing strain is removed. If you were to drop a steel ball on a very hard surface, it would probably bounce higher than than rubber. If you drop it on a softer surface, ...
Though units for pressure and stress are same (i.e N/mm2)What is the difference between stress and pressure?
Latest Answer: Pressure is exerted only in case of fluid, liquid or gases, but stress is exerted only on solid. ...
