It operates on the principle, that a very slight upward pressure on the spindle at the contact point is multiplied through a system of gears and levers. It is indicated on the face of the dial by a dial finger. Dial indicators consists of a body with a round graduated dial and a contact point connected with a spiral or gear train so that hand on the dial face indicates the amount of …

Micrometer screw gauge uses a calibrated screw is used for precise measurements. the accuracy of the micrometre screw gauge is 0.01. Most of the engineering works have to require more precession. o screw gauge is the suitable instrument that achieves the required accuracy.

The principle used in a four stroke petrol engine is commonly known as Otto Cycle. It states that there would be one power stroke for every four strokes. Such engines use a spark plug which is used for the ignition of the combustible fuel used in the engine. Most of the cars, bikes and trucks use a 4 stroke engines.

For the working principle, there are only two steps. However, technically this two stroke engine also has 4 processes, where each step will take 2 processes. 1. Upward stroke. The upward stroke is a step that piston move upward from BDC (bottom dead center) to TDC (top dead center). In this stroke there are two steps, the intake step and ...

Explain in detail principle, construction and working of Radiation Pyrometer with neat sketch. Last Answer : Radiation pyrometer Principle: According to Stefan Boltzmann's law, the intensity of radiant energy emitted by a hot target varies as the fourth power of its absolute temperature. is calibrated in terms of target temperature by using either a voltmeter or Wheatstone bridge circuit.

A solar cell is basically a junction diode, although its construction it is little bit different from conventional p-n junction diodes.A very thin layer of p-type semiconductor is grown on a relatively thicker n-type semiconductor.We then apply a few finer electrodes on the top of the p-type semiconductor layer.. These electrodes do not obstruct light to reach the thin p-type layer.

The working principle of a centrifugal pump is based on forced vortex flow. The forced vortex flow means that when a certain mass of fluid rotates by an external force (leading to an external torque), there is an increase in the pressure head of the liquid.

Divide the circumference of the screw into a number of fine parts. let's say 100 parts on the circumference. and the pitch of the screw is 1mm then The minimum length can be measured the screw gauge = Screw pitch/ Number of parts the circumference = 1mm/100 = 0.01

Principles of Rolling: The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction. This gap is smaller than the thickness of the part being worked. Therefore, the rollers compress the metal while simultaneously shifting it forward because of the friction at the roller-metal interfaces.

Explain the working principle of turbojet with neat sketch. Answer: Working principle of Turbojet: shows the schematic of turbojet engine. It has a diffuser section at inlet for realizing some compression of air passing through this section. Due to this air reaching compressor section has pressure more than ambient pressure.

Because the simple Pitot tube (Above Figure ) only samples a single point, and, because the flow profile of the fluid (and hence velocity profile) varies across the pipe, accurate placement of the nozzle is critical. To avoid this type of problems we are using averaging pitot tubes. Note that a square root relationship exists between velocity and pressure drop (see …
