# Problem: A 70 kg man walks out on a 10 kg beam that rests on but is not attached to two supports. When the beam just starts to tip what is the force exerted on the beam by the right support?

###### FREE Expert Solution

Newton's second law:

$\overline{){\mathbf{\Sigma }}{\mathbf{F}}{\mathbf{=}}{\mathbf{m}}{\mathbf{a}}}$

When the beam starts to tip, all the downward forces are balanced by the right support.
