To construct a triangle given the base, the difference of the other two sides and one base angl..

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 copper half ring..

Through A, B and C draw lines parallel to BC, AB and AC respectively. Let these lines meet at P, Q and R forming D PQ..

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 - 3 - To construct angles of 60 o , 120 o and 30 o (i) Draw a line AB. (ii) With A as centre, taking any suitable radius, draw an arc which cuts AB at P. (iii) With P as centre and the same radius, cut the arc at Q. (iv) From Q, with the same radius, cut the arc at ..

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 = 3.8 cm and..

Construction - 14 - To construct a right angled D ABC when hypotenuse AC = 4 cm and hypotenuse and one acute angle are given (1) Draw a straight line AC = 4cm. (2) Taking OC as diameter, draw a semi circle on AC. (3) At A, construct meeting the semicircle at B..

Construction - 5 - To construct angles of 75 o and 105 o (i) Draw AB. Make any point O on it. (ii) With O as centre, draw an arc which cuts AB at B. (iii) With B as centre and same radius, cut an arc at Q and from Q with same radius, cut the arc at R. (iv) Jo..
