document.write( "Question 1173898: The distance (d) a spring will stretch varies directly as the force (F) applied to the spring. If a force of 12 lb is required to stretch a spring 3 in., what force is required to stretch the spring a = 8 in.? \n" ); document.write( "

We can use ratios for this question.
\n" ); document.write( " $\"%28lb_of_force%29%2Finches\"$ \r
\n" ); document.write( "\n" ); document.write( "We know that 12 lb of force give 3 inches of stretching so we can input that into the ratio.
\n" ); document.write( " $\"12%2F3\"$
\n" ); document.write( "Now we can input the other piece of information we know on the other side of the equation.
\n" ); document.write( " $\"%2812%2F3%29=%28x%2F8%29\"$
\n" ); document.write( "Now we just solve the equation.
\n" ); document.write( "x= $\"%2812%2A8%29%2F3\"$
\n" ); document.write( " =32\r
\n" ); document.write( "\n" ); document.write( "Therefore 32 lb of force is required to stretch the spring 8 inches. \n" ); document.write( "

\n" );
