cl ENTRANCE EXHIBITIONS ן III -jfffletfjantrt Clothworkers' Exhibition only Explain clearly what is meant by the velocity of one moving point relative to another moving point and shew by an example how to find the relative velocity when the direction of the velocities of the two moving points are not the same What is the acceleration of point which changes its velocity from feet per second to feet per second in second and what is the velocity of the point after seconds Over smooth pulley passes light string having at each end scale-pan of mass grms mass of 10 grms is placed in one pan and mass of grms in the other find the tension of the string and the pressure on the pans in dynes 980 cm per second per second Define momentum work and energy and state how they are measured mass of lbs strikes horizontal plane with velocity of 20 feet per second at an angle of 30 to the horizon Find where the mass will strike the plane again and the loss of energy by the first impact Coefficient of elasticity The unit of energy is that of body of mass grms after being acted upon by force equal to the weight of grms for $th of second The unit of velocity is that of body which has fallen vertically through metres Find the unit of mass From the theorem known as the parallelogram of forces deduce that known as the triangle of forces Two masses of and grms are suspended respectively from two points and Β of string which has its ends fixed to two points and The two parts AC BD of the string make angles of 30 and 60 respectively with the vertical and the part AB is horizontal the whole being in one vertical plane Find the tensions in the different parts of the string lamina is formed by describing equilateral triangles on two adjacent sides of square of side 2a Find the distance of the centre of gravity of the whole from the centre of the square
