Plane and block

  1. Apr 7, 2013 #1
    I have some theoretical questions that I can not answer for a proper understanding of the situation... Can you help me please?

    We have a system - a wheel of a plane and a block http://fykos.cz/rocnik26/obrazky/s5u4_zadani.png

    The plane begins to move. May be a situation where plane is going to full throttle but still is in a same place (cause the block)? How it depends on the wheel material, the block and the floor? My friend said it is a special case when the block is high just on the touch of wheel. What will happen?

    Thanks and sorry for my bad English,

    Your English is excellent but your link will not open and I'm not sure I understand your question. Are you talking about an airplane, that has a block against each wheel preventing it from moving? What is holding the block in place? If the block is low enough, the wheel can just step onto and over the block.
