You can put this solution on YOUR website!
If the advantage = the ratio, you need the quotient of the two piston AREAS. Pistons are generally circular, though that is not stated. If so calculate the areas from their diameters since:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"A=pi%2Ar%5E2\"
\n" ); document.write( "Remember that r or the radius is half the diameter.\r
\n" ); document.write( "\n" ); document.write( "First piston:
\n" ); document.write( "\"A=pi%2A1.55%5E2\"
\n" ); document.write( "\"A=pi%2A1.55%5E2\"
\n" ); document.write( "\"A=3.14159%2A2.403\"
\n" ); document.write( "\"A=7.55+cm%5E2\"\r
\n" ); document.write( "\n" ); document.write( "Second piston:
\n" ); document.write( "\"A=pi%2A1.125%5E2\"
\n" ); document.write( "\"A=pi%2A1.125%5E2\"
\n" ); document.write( "\"A=3.14159%2A1.27\"
\n" ); document.write( "\"A=3.98+cm%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Mech advantage = The ratio of the piston areas\r
\n" ); document.write( "\n" ); document.write( "Advantage = 7.55 cm^2/3.98 cm^2
\n" ); document.write( "Advantage = 1.90\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
