Pushing and pulling question

  1. Jul 21, 2017 #1
    So if in an ordinary bus, is it easier to open a window by pushing it upward while seated or by pulling it upward while standing?

    Question came up in our exams today. I answered while seated. Not quite sure though.

    Welcome to the PF.

    It depends on what is meant by "easier", but from an ergonomic standpoint, doing it seated would put less strain on your back in general, IMO.

    Not just strain on your back, but lifting it while standing would largely rely on wrist flexor muscles which are not as strong as the triceps that would be the key muscle group for the seated approach (I think)
