Integration of Equations

  1. Nov 22, 2008 #1
    Hey, need some help on a problem, think its classed as integration, but may be wrong?

    I have formulated this equation, but dont know how to get to the next step

    [tex]\therefore\: -MA*1 + RA \frac{1^2}{2} - 29.43 * 0.4 - 19.62 * 0.85[/tex]


    This is a similar equation that has been solved

    [tex]\therefore -\;MA * 20 + RA * \frac{20^2}{2}- \frac{20^3}{8} + \frac{10^3}{8} -6 * 5^2\;=\;0[/tex]

    and here is the solution

    [tex] \displaystyle \therefore\;\;\;\;\;\;10\;R_a\;-\;M_a\;=\;\frac{205}{4} [/tex]


    ----

    I dont know, and cant figure out how to achieve this result for the top formula? Calculus is not my strong point at all.

    This is not homework, this is related to a problem i am trying to solve.

    Thanks for any help

    I would recommend that you first take the time to write out the problem. What you have is NOT an equation and you give no idea WHAT you want to do.

    Also, because this has nothing to do with either calculus or differential equations, I am moving it to the "general math" section.
