    I have an answer to this question, but it just doesn't seem like it could be right. Can someone please have a go for me?

    A picture weighing 40N is suspended by means of a string passing round a nail, each part of the string making an angle of 60 degrees with the vertical. Calculate the tension in the string.

    Hmmm... and surely the tension is just going to be the weight as there are no acceleration forces on the string?

    Oh soz! Is this M1 or M2.. I'm gonna start revising M2 tomoz

    Wouldn't it just be 20 / cos60 ?

    I got 40N, and I got this by resolving vertically.
    ( 2Tsin30=40, Tsin30=20, T=20/sin30)

    Ahh I got 20/sin30, which is the same thanks!

    I'm completely stuck on the next question, if either of you are really bored..

    A uniform ladder of weight 200N AND 10m long rests with one end on the ground at an angle of 60 degrees to the horizontal, with its upper end resting on a smooth wall. Find the reactions at the wall and the ground.

    I know there's a simple solution, and my teacher went over whole load of ladder situations a couple of lessons ago, so I feel really stupid!
