684 AiTLIED SCIENCES Find the form of the line of resistance in suspension bridge in which the load is uniformly distributed along the horizontal roadway and show that it is parabola Find the volume and surface of ring formed by the revolution of circular disc about tangent to the disc FIRST YEAR Explain why bodies of different weight fall at the same rate 1ו κίΐ יז6מ Through what height must heavy body fall from rest in order to acquire velocity of 322 ft per second If it con tinue falling for another second after having acquired the above velocity through what distance will it fall in that time Explain what is meant by the terms velocity and acceler- ation Assuming that velocity and an acceleration are expressed by the numbers 12 and 16 respectively when ft and sec are taken as units of space and time by what numbers will they be expressed when ft and £ sec are taken as units Distinguish between weight and mass If the weight of certain mass be represented by 20 at place where body falls through 64 ft in sees what will be the weight of the same mass at place where body falls through 180 ft in sees Shew how to determine the relation between Power Weight and Pressure on an inclined plane when the Power acts parallel to the plane ύ when its acts parallel to the base of the plane Explain the meaning of the equation ITg In Attwood's machine two masses of 20 and 24 grammes were suspended in two scale pans at the extremities of the string Determine the acceleration the distance traversed in sees and the tension of the string Two stones are thrown at the same instant from the top of cliff each with velocity of 64 ft per second The
