660 APPLIED SCIENCES the vertex to the axis is in find the volume of the ring traced out by the triangle In the first system of pulleys there is one movable pulley turning on rough axle find the mechanical ad- vantage when weight is raised by means of it Find the weight raised by force of 10 lbs the radius of the pulley being in of the axis in and the limiting angle of friction the angle whose sine is Draw diagram of forces for the framework ACB which supports roof If the angle ACB is right angle and CFG an equilateral triangle find the strains along the several pieces 10 Find the moment of inertia of cylinder of given length and radius about one of its gOnerating lines If the cylinder be set oscillating about the generating line as an axis find the angular velocity acquired in falling from its highest to its lowest position FIRST YEAR Explain what is meant by the terms velocityי and ac- celeratiom Assuming that velocity and an acceleration are expressed by the numbers 12 and 16 respectively when ft and sec are taken as the units of space and time by what numbers will they be expressed when ft and sec are taken as units
