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.
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.

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...
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?
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?
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...
