<p>Even a “strict technical institute” will have some liberal arts because:</p>
<ol>
<li> Math and natural science are needed prerequisites to engineering.</li>
<li> Humanities and social studies requirements in the engineering degree program are required for ABET accreditation (even Brown, with no breadth requirements generally, requires humanities and social studies breadth for engineering majors).</li>
</ol>
<p>However, what it appears that you are really looking for is a large selection of quality offerings in whatever liberal arts you are interested in. Is that correct? If so, then any school that is good in both engineering and the liberal arts you are interested in will be good for this purpose. And that means a lot of schools quality, including many of the big state universities.</p>
