    The part a) of the question I do not understand is the horizontal force.

    If the horizontal forces acts on the parcel, I thought the vertical force component (50sin10) will be going UP rather than down as it says in the answer. So in my words I thought..

    R + 50sin10 = 4gcos10.. R = 4gcos10 - 50sin10

    Can someone explain why the vertical component of the Horizontal force is down rather than up?

    draw this force as a pulling force rather than a pushing force and this might make more sense

    as I will be off to bed soon look also at some worked out examples to help you, particularly with reference to the "pushing force"

    thanks a lot for replying, i think i get the general gist of it, but I don't understand the vectors part

    this picture shows you my thinking of why my mind keeps telling me the vertical component is upwards

    yeah i looked at that and posted after, i still don't understand the work behind the vertical component being downwards rather than upwards, sorry for dragging this
