You can put this solution on YOUR website!
lets call the strength of the beam s and the length L
\n" ); document.write( ":
\n" ); document.write( "sL=k
\n" ); document.write( ":
\n" ); document.write( "100(5)=500
\n" ); document.write( ":
\n" ); document.write( "so our constant of variation is 500
\n" ); document.write( ":
\n" ); document.write( "s(8)=500
\n" ); document.write( ":
\n" ); document.write( "s=62.5kg \n" ); document.write( "

\n" );
