APPLIED SCIENCES 671 Define work body weighing 80 lbs is projected along rough horizontal plane with velocity of 50 ft per sec the coefficient of friction find the work done against friction in sec beam 16 ft long and weighing 40 lbs balances by itself about point ft from one end If to this end weight of 100 lbs be hung find the least force applied at the other end that will support this weight What is meant by the energy of moving body body of given mass is projected up plane 10 feet long which is inclined at an angle of 30 to the horizon with velocity of 20 feet per second find the velocity at the top of the plane In the first system of pulleys when there is one moveable and one fixed pulley find the accelerations and tension of the string when mass of lbs raises mass of lbs When two forces acting on point are represented in direction and magnitude by two sides of parallelogram show that the resultant is represented in magnitude by the diameter of the parallelogram square picture frame is suspended at two corners by string which is hung over smooth peg in such way that the lengths of the two parts of the string are in the ratio of to find the inclination of the sides of the frame to the vertical -iiflanufactttrtng &rt antt ffiiacfymvv SECOND YEAH Sketch section through the cylinder of hydraulic press showing the method of packing the ram Describe the machinery used at Woolwich Arsenal for pressing the felloes and spokes of wooden wheels together Having computed the quantity of steam required per minute in the cylinder of an engine state approximately the quantity which must be added for waste and useless resistances
