Homework Help: Dot Product of two Vectors

  1. Aug 31, 2011 #1
    1. The problem statement, all variables and given/known data
    obtain the dot product of the two vectors F= 10i + 6j - 3k lb and B= 6i -2j ft

    2. Relevant equations
    F dot B = FxBx + FyBy + FzBz
    x is for the x components
    y is for the y components
    z is for the z components

    3. The attempt at a solution
    F dot B = (60 + -12 + 0)
    I ended up with 48 lb-ft. I really just want someone to check my work. thanks
