why you cannot push solid

Just about every (but not all) solids expand with an increase in temperature. Why? Before going to the answer, let's look at a common model of a solid - the ball and spring model.
The contact force with some solid isn't constant. The more something pushes against material, the greater this constant force becomes.
When you pull on a metal, it stretches.
The speed of sound is different in different materials.

YOUR ANSWER__.:-)
The reason it can't be pushed ordinarily is because it's not rigid, in physics terms, it buckles under the slightest force (including its own weight). That means that, if you try to impart a force to it, the shape changes, and your force is not translated in the direction you want it to go...
Pushing translates force only on a rigid object, which a rope is not. Rigidity and strength are totally different concepts, so a rope can translate force along it's length, but won't keep its shape if pushed.
i hope its help U:-)
