APPLIED SCIENCES 659 same mass at place where body falls through 101 '25 ft in sees body is projected vertically upwards with velocity of 96 ft per sec How loug will it be in rising to three-fourths of its greatest height and how long will it be before it reaches the ground again uniform bar weighs grammes per centimetre Find its length when weight of 25 grammes suspended at one end keeps it in equilibrium about fulcrum 12 centimetres from the other end Shew how to determine the relation between Power Weight and Pressure on an inclined plane when the Power acts parallel to the plane when it acts parallel to the base of the plan Explain the meaning of the equation Mg In Attwood's machine two masses of 50 and 51 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 What is meant by the Energy of moving body State the principle of Conservation of Energy With single fixed pulley and single movable pulley mass of 15lbs draws up mass of 12 lbs find the accelerations and the tension of the string during the motion State and prove the principle known as the triangle of forces heavy uniform ladder weighing lbs and feet long stands on rough floor with its upper end pressing against smooth vertical wall at point feet above the floor find the magnitude and direction of the pressure on the floor When two parallel forces act on different points of body shew that the sum of their moments about any point in their plane is equal to the moment of their resultant about the same point Explain what occurs when the forces are parallel but directed opposite ways not along the same line of action The lengths of three uniform rods forming triangle are τ τ
