A 3.0-m-long rigid beam with a mass of 100 kg is supported at each end. A(adsbygoogle = window.adsbygoogle || []).push({});

80 kg student stands 2.0 m from support 1. How much upward force does support 1 exert on the beam?

I first found the weight of the student to be 784N.

so 784N*2cm =F*3cm

F= 522.67N

is this right?
