Answer
$$200\ in .$$
Work Step by Step
The lever priciple states that
$$F_1d_1=F_2d_2.$$
Making use of the fact that $1~ton =2000~lb$, we convert $3~tons$ into $3*2000=6000~lb$. Then, we plug in the given values to get:
$$ 6000\times 11=330\times x\Longrightarrow x=\frac{ 6000\times 11 }{330}=200\ in .$$
