cx ENGINEERING DEPARTMENT Find the equation to the line of resistance in wall of brickwork of rectangular section and given thickness which sustains the thrust Ρ of roof in direction inclined 30 to the horizon on its inner edge FIRST YEAR Distinguish between velocity and acceleration If body moves with uniformly accelerated velocity what is the measure of the velocity at any moment The velocity of body increases from 200 ft per minute to 600 ft per minute in seconds find the acceleration in foot second units in yard minute units ball is let fall from the top of ship's mast 36 ft high The ship is sailing at the rate of 12 miles an hour How far does the ship sail during the time the ball is falling The sum of the two masses in an Atwood's Machine is lbs and the difference between them is an ounce find the velocity and the space described after seconds Find also the tension of the string during the motion Define work י and energy What is the energy of train of 40 tons moving at the rate of 20 miles per hour What force acting for one minute would be sufficient to bring the train to rest pair of nut-crackers is inches long and nut is placed of an inch from the hinge what pressure applied at the ends will crack the nut if weight of 20 lbs when simply placed on the top of the nut will crack it Three movable pullies and one fixed one each having mass of lb are arranged according to the first system according to the third system determine the mass which can be supported by mass of lbs State the triangle of forces Employ it to determine the tensions of the strings and their inclinations to the horizon when mass of 28 lbs is tied on string 21 inches
