    Unit reduction is not making sense, what's going on?

    You are correct, Tim. The g in this equation is used for converting lbm to lbf. Once you go into SI units, it is unnecessary. Thanks for everyone's help.

    Unit reduction is not making sense, what's going on?

    I am using an equation that states that critical sonic velocity is: a_{cr}=\sqrt{\frac{2\gamma}{\gamma+1}gR_{gas}T'} The units should result in velocity (\frac{m}{s}) Yet, when I do the unit reduction I do not get that answer. Here is what I get: Lets ignore the square root for now. Also...

    Evaluating a Reversed Order Double Integral

    Homework Statement Eveluate by reversing order of integration \int^{2}_{0}\int^{1}_{y/2} ye^{x^3}dxdy Homework Equations The Attempt at a Solution this is what I got... \int^{1}_{0}\int^{2x}_{0} ye^{x^3}dydx I end up with... \int^{1}_{0} 2x^2e^{x^3}dx I don't know...

    Finding the Minimum Distance for Static Equilibrium with a Hanging Weight

    so, 0 = -2Fg + 4Ff - (4-x)(Fg) 0 = Tx - N 0 = Ty + Ff - 2Fg Are these correct? I have no idea where I'm going with this... should it end with a finite number or will it have variables in it?

    Finding the Minimum Distance for Static Equilibrium with a Hanging Weight

    there's weight of beam, weight of sphere, tension, normal, friction. Friction is at the left, tension at the right. Isnt the pivot at the right end, so TORQUEnet = 0(Tension) - 2Fg + 4Ff - x Fg and TORQUEnet = 0 so that it is in equillibrium?

    Finding the Minimum Distance for Static Equilibrium with a Hanging Weight

    okay so 0 = 2Fg + 4Ff - xFg N = Tension in X direction Ff = N (Mu) = (tension in X)(Mu) I don't get how to calculate tension =/

    Finding the Minimum Distance for Static Equilibrium with a Hanging Weight

    Homework Statement One end of a uniform 4.00-m-long rod of weight Fg is supported by a cable. The other end rests against the wall, where it is held by friction, as in Figure below. The coefficient of static friction between the wall and the rod is s = 0.500. Determine the minimum distance...
