    Can anyone help me with this question? I know that the sum of clockwise moments equals the sum of anti-clockwise moments.
    But what would you multiply by what? For example, what distance would you multiply 230N by? Would it be 4.25m?

    It's a uniform beam so the weight will act through the centre of mass in the middle on the beam, ie. 5m from each end, 4m from the wall on the left. If you take moments about that wall, you can figure out the support force from the other wall.

    Excuse me? I'm a human, not the mean value property. That's some weird ass topographical stuff. I'm not weird ass topographical stuff. Rude.
