construction 2

Construction - 2 - To bisect an angle , we are required to bisect (i) With B as centre and any suitable radius draw an arc to cut AB at D and BC at E respectively. (ii) Take any radius greater than of ED, not necessarily the previous radius. (iii) With this radius, taking points..

A simple D.C. generator consists of a rectangular coil ABCD which can be rotated rapidly between the poles N and S of a strong horse-shoe type magnet M. The generator coil is made of a large number of turns of insulated copper wire. The two ends of the coil are connected to the two..

'S' is a large spherical conducting shell of radius few meters. C 1 and C 2 are the two supporting pillars. An insulating material like silk acts like a conveyor belt wound over two pulleys P 1 and P 2 . The pulleys move with the help of a motor. B 1 and..

It consists of a soft iron core made of laminated sheets well insulated from each other. The coils P 1 P 2 and S 1 S 2 are wounded on the same core. The coil P 1 P 2 is a primary coil connected to AC source and S 1 S 2 is a secondary coil connect..

It consists of N turns of coil PQRS wound over a non-magnetic metallic frame usually rectangular or circular. The coil is suspended from a torsion head H by means of phosphor bronze strip in a magnetic pole by pieces N and S. A mirror M is attached to the phosphor bronze strip. The other end of th..

Construction - 13 - To construct an isosceles when altitude CD to the base AB is 2 cm and the vertical angle C = 90 o (1) Take any straight line XY and at any point D on it, draw cutting off DC = 2 cm. Join DC. (2) At C, on either side of DC, c..

Construction - 12 - To construct when , AC = 4 cm, BC = 4.8 cm, two sides and the angle opposite to one of them are given. (1) Draw a straight line AX (2) At A, Construct (3) From A, cut off AC = 4 cm. (4) From C, cut off CB = 4.8 cm, B lying on AX...

Construction - 15 - To construct a triangle when the sum of two sides, the remaining side and the angle between them are given (We assume that the given angle can be constructed with ruler and compass alone) In BC = 3.8 cm, and AB + AC = 6.5 cm (1) Draw BC = ..

Two waves are said to interfere constructively or reinforce each other, if the resultant amplitude is maximum. The condition for constructive interference is that the phase difference A phase difference of 2 p corresponds to a path difference l . Let the phas..
