Just looking at the June 09 paper, and they mention "thrust in the two bar". I've never come across thrust in any book for M1.

So can someone explain the basic principles of thrust for me? How, when, where it reacts?

It also made Tension disappear.

Thrust is the opposite of tension. If a rod (e.g. towbar) is being squashed, as when a car and caravan are braking, the towbar will push on both vehicles rather than pulling on them. So the arrow for the force at each end of the towbar will be towards the vehicles (rather than away from them if it were a tension).

Well driving force is 0 and thrust acts as 100N in two places

I can't understand why teachers are not giving out the recent papers (assuming they are not still keeping them for mocks). The last 3 or so Edexcel M1 papers have contained several ideas that are different in style from the previous ones. It is therefore important that candidates have worked through these papers.

Ditto... we had never covered it at all! I spent so long just thinking that one question had ruined the whole thing.

OP, basically it is the opposite of tension, so just acts in the opposite way to it

So tension is ignored/goes away and there is only thrust? I think I used both tension and thrust in the actual exam so got it wrong.

Strings can only pull (pull = tension).

Rods can pull or push (push = thrust). (Imagine background titter from AS class of boys).

It also made Tension disappear.
It's the force acting on an object when it's being pushed. (Compression)
Unlike tension, which is the force acting on an object when it is being pulled along by a string.

Thrust. :sexface:

It basically comes about as a result of an inequality between two supposed integers. The tension disappears after the problem is worked through and normalised, which you do by equalising the problematic problem.

So is tension present when the connected particles are accelerating and thrust when they are decelerating??
