Find the speed of the wheel if its diameter is 28 inches. \n" ); document.write( "** \n" ); document.write( "By dimensional analysis: \n" ); document.write( "rad=radians, rev=revolution, 2πr=circumference, r=radius=28/2=14 in \n" ); document.write( "speed of wheel=16 rad/sec*rev/2π rad*2πr/rev \n" ); document.write( "rad, rev and 2π cancel out \n" ); document.write( "=16r in/sec \n" ); document.write( "=16*14 in/sec \n" ); document.write( "=224 in/sec \n" ); document.write( " |
