Homework Help: Quick Mechanics Question

  1. Mar 22, 2010 #1
    1. The problem statement, all variables and given/known data
    I have a Matlab project that deals with some stuff that I've yet to cover in mechanics so I'm not really sure about some of the equations being discussed. What I have a question about is what the capital T means in the following equations. I honestly have no clue what it means. I've tried looking it up but no luck.

    2. Relevant equations
    "let x be the vector of displacements and P the corresponding vector of forces at pin joints." u is the x displacement, v is the y displacement, P is the x force, Q is the Y force.

    [tex]x=[u1 v1 u2 v2......]^T[/tex]
    [tex]P=[P1 Q1 P2 Q2......]^T[/tex]

    This T also shows up in a few equations. Such as

    [tex]P^T x= F^T \delta[/tex]

    3. The attempt at a solution
    I tried google not really sure what to search for.

    I'm not familiar with Matlab and I don't know about your "pin joints" problem, but I will take an educated guess that the T stands for matrix transpose.
