It occurs particularly in the seams of rivetted joints and around the rivet holes.
The aim is to share an expensive resource.
The input impedance of a centre-fed half-wave dipole is : (a) 300 W (b) 288 W (c) 75 W (d) none of these.Explain Full duplex and half duplex.(a) it cannot be determined from the given data (b)4dB (c) 216 dB (d) 110Db.Ans: It is used to measure the total hemispherical solar radiation.The result is a clipped copy of the alternating current waveform with only positive voltage, and an average voltage that is one third of the peak input voltage.Which factors influence the type of fracture in failure of a material?Graphite has a hexagonal layer lattice.The junction diodes capacitance revistas em pdf gratis that is made use of in varactors is known as (a) transition capacitance (b) diffusion capacitance (c) space charge capacitance (d) inter-electrode capacitance.A UJT relaxation oscillator circuit produces a sawtooth like waveform (a) at B1 terminal (b) at B2 terminal (c) across the capacitor (d) none of these.It exists in ordinary steels at elevated temperatures, but it is also found at ordinary temperatures in some stainless steels.
How convective heat transfer is effected and on what factors it depends?
Column is always vertical but strut as member of structure could carry axial compressive load in any direction.
Ans: For subsonic flow at inlet section of a diffuser a lower velocity and higher pressure will exist at the exit section.In electronics, a diode is a two-terminal device.Ans: Temperature increases and pressure decreases.Ferrite stabilisers have the effect of extending the temperature range over which alpha and delta ferrite are formed, which consequently reduces temperature range over which austenite is formed.Ans: Grey cast iron with tensile strength of 250 MPa.When the voltage of the alternating current is positive, the diode becomes forward-biased and current flows through.Digital on the other hand is breaking the signal into a binary format where the audio or video data is represented by a series of 1s and.SCRs are connected in series to enchance (a) their overall dv/dt rating (b) their voltage ratings (c) their current handling capabilities (d) none of these.The Microcell is used to improve capacity in areas where demand to make calls is high, such as shopping centres.
Explain the formation of microstructures of pearlite, bainite and martensite in steel.
