Physics problem- need help

<p>I've noticed a couple physics threads here, heh. Anyway, I'd appreciate it if anybody could help me with the following problem:</p>

<p>A uniform steel beam has a mass of 1900 kg. On it is resting half of an identical beam, as shown in Fig. 9-50 (click on link). What is the vertical support force at each end?</p>

<p>My friends and I have been stuck on this, and it would be nice if anybody knew how to do it. Thank you in advance.</p>

<p>I dont want to solve it but the easiest way to do it is to think of it as a centriptal problem instead of a tangential (linear) problem.</p>

<p>Assume that the center of gravity for the "M" beam is in at L/2, and the center of gravity for M/2 is at L/4 (from left to right).</p>

<p>It's actually way easier if there's an angle. sorry i can't be much help</p>

<p>I got the answer. Thanks.</p>
