Grabber - statics example


We should get the length x , when the grabber can just hold the box.


I made two moment equations:


Then I put them together into one equation: m1m2

And from that equation I found out x: x

Unfortunately the result seems to be wrong. Can you please help me? Where I made the mistake?

Romel's picture
$\Sigma M_H = 0$

$\Sigma M_H = 0$

$(x\sin \alpha)(\frac{1}{2}G) + \frac{1}{2}G(\frac{1}{2}b) = \dfrac{G}{2\mu_0}(l_1 + l_2)$

$x = \dfrac{2(l_1 + l_2) - \mu_0 b}{2\mu_0 \sin \alpha}$

Thank you very much sir!

Thank you very much sir!

It is the right solution and now when I have understood it, it looks so much simplier than before.
