The maximum frictional force, which comes into play, when a body just begins to slide over. the surface of the other body, is known as limiting friction.

When one of the links of a kinematic chain is fixed, the chain is known as mechanism. It may be used for transmitting or transforming motion.

The Kaplan turbine is a propeller-type axial flow reaction water turbine which has adjustable blades.
It was developed in 1913 by Austrian professor Viktor Kaplan, who combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level.
Since it is a reaction turbine, so the reaction force of leaving water is used to turn the runner of the Kaplan turbine, As the water flows through the twisted blades a lift force is generated in the opposite direction of the leaving water and that lift force causes the blades to rotate.

Potential energy = Mass x accelaration due to gravity x Height = mgh =5 x 9.8 x 20 = 980j

Mandatory signs are road signs which are used to set the obligations of all traffic which use a specific area of road. Unlike prohibitory signs, mandatory signs tell traffic what it must do, rather than must not do. Most mandatory road signs are circular, may use white symbols on a blue background with white border or black symbols on a white background with a red border, although the latter is also associated with prohibitory signs.

Current flows through a switch to the load, such as a ceiling light. When you flip the switch off, it breaks the circuit and interrupts the flow of electricity. A basic light switch has two terminals and sometimes a ground terminal. The hot wire from the power source is connected to one of the terminals. So it is controlling accessories

Adiabatic process, in thermodynamics, change occurring within a system as a result of transfer of energy to or from the system in the form of work only; i.e., no heat is transferred.
A rapid expansion or contraction of a gas is very nearly adiabatic.
Adiabatic process -A process in which the system is insulated from the surroundings and no heat flows between the system and the surroundings.
(ie, ?Q = 0)

Cantilever beam having uniformly distributed load on the entire length, then the maximum Bending moment will be at the fixed end.

Its job is to block the flow of coolant to the radiator until the engine has warmed up. When the engine is cold, no coolant flows through the engine. Once the engine reaches its operating temperature (generally about 200 degrees F, 95 degrees C), the thermostat opens.

The Dew Point temperature is always lower than the Dry Bulb temperature and will be identical with 100% relative humidity (the air is at the saturation line). As air temperature changes the Dew Point tends to remain constant unless water is added or removed from the air.
