MCQ->The simplest method of welding two pieces of metal together is known as pressure welding.The ends of a metal are heated to a white heat-for iron,the welding temperature should be about 1300C-in a flame.At this temperature the metal becomes plastic.The ends are pressed or hammered together,and the joint is smoothed off.Care must be taken to ensure that surfaces are thoroughly clean first,for dirt will weaken the weld.Moreover,the heating of iron or steel to a high temperature cause oxidation,and a film of oxide is added to the heated surfaces.For this reason,flux is applied to the heated metal.At welding heat,flux melts and the oxide particles are dissolved in it together with any other impurities which may be present.The metal surfaces are pressed together,and the flux is squeezed out from the center of the weld.A number of different types of weld may be used,but for fairly thick bars of metals,a vee-shaped belt should be normally employed.It is rather stronger than ordinary butt weld. The simplest way of welding two pieces of metal together is...
MCQ-> Study the following information carefully and answer the questions given below:Eight friends P, Q, R, S, W, X, Y and Z are sitting around a circular table but not necessarily in the same order. Some of them are facing the centre and some others are facing outside (i.e. in a direction opposite to the centre.) Note :(i) Facing the same direction means if one person faces the centre then the other also faces the centre and vice-versa. (ii) Facing the opposite directions means if one person faces the centre then the other faces outside and vice-versa. (iii) Immediate neighbours facing the same direction means if one person faces the centre then the other also faces the centre and vice-versa. (iv) Immediate neighbours facing the opposite directions means if one person faces the centre then the other faces outside and vice-versa. • R sits second to the right of Y. Only two persons sit between R and W. • P sits to the immediate right of W. W faces outside. • Only one person sits between P and Z. Immediate neighbours of P face opposite directions. • Q sits third to the left of Z. Q is not an immediate neighbour of P. • X faces a direction opposite to that of Y. X is an immediate neighbour of neither Y nor P. • Immediate neighbours of S face same direction. P does not face outside. • R and Q face a direction opposite to that of S.Four of the following five are alike in a certain way based on the direction they are facing and so form a group. Which is the one that does not belong to that group?

MCQ-> Study the following information carefully and answer the questions given below: Eight friends — J, K, L, M, N, 0, P and Q — are sitting around a circular table but not necessarily in the same order. Some of them are facing the centre and some of them are facing outside. (i.e. in a direction opposite to the centre.) Facing the same direction means if one person faces the centre then the other also faces the centre and vice-versa. Facing the opposite direction means if one person faces the centre then the other faces outside and vice-versa. Immediate neighbours facing the same direction means if one neighbour faces the centre then the other also faces the centre and vice-versa. Immediate neighbours facing the opposite direction means if one neighbour faces the centre then the other faces outside and vice-versa. • Only one person sits between K and 0. Q sits third to the right of 0. • M sits to the immediate right of Q. Q faces outside. • L sits second to the left of P. P is not an immediate neighbour of 0. • L faces a direction opposite to that of 0. Immediate neighbours of L face opposite directions. • J sits third to the left of N. J is not an immediate neighbour of P nor K. • M and J face a direction same as that of N.Four of the following five are alike in a certain way based on the directions they are forming and so form a group. Which is the one that does not belong to that group?

MCQ-> Study the following information carefully and answer the questions given below :Eight persons — A, B, C, D, P, Q, R and S — are sitting around a circular table with equal distances between each other (but not necessarily in the same order). Some of them face outside and some others face the centre. NOTE : Facing the same direction means if one faces the centre then the other also faces the centre and viceversa. Facing the opposite directions means if one faces the centre then the other faces outside and viceversa. Immediate neighbours face the same direction means if one neighbour faces the centre then the other neighbour also faces the centre and viceversa. Immediate neighbours face the opposite directions means if one neighbour faces the centre then the other neighbour faces outside and viceversa. P sits to the immediate right of C. Only three persons sit between P and A. R sits third to the left of A. Neither A nor C is an immediate neighbour of B. D sits to the immediate left of B. Q sits second to the left of D. The immediate neighbours of A face the same direction. The immediate neighbours of B face opposite directions. S sits second to the right of P. The immediate neighbours of C face the same direction. S faces outsideFour of the following five are alike in a certain way based on the given sitting arrangement and so form a group. Which is the one that does not belong to that group?
