A staging that weighs Wstaging supports a painter weighing 620 N. The reading on the left scale is 660 N and the reading on the right scale is 410 N. What is the weight of the staging? Answer in units of N

  • physics -

    Make a free body diagram of the staging.

    Sum forces acting on the staging, and the total should be zero.

    Upward (reaction) forces=660+410=1070 N
    Downward forces = 620 N + W
    Sum to zero
    620+W=660+410
    W=660+410-620
    =450 N.
