In this question we have to find the shear flow at point a and point b from the figure and when there is a shear force of 5kip applied to the beam.
00:14
First if we take a look at the figure in the textbook, we can calculate the y bar, which is to place that the neutral axis b.
00:26
It is equal to sigma y bar a divided by 6.
00:31
Sigma 8 and that is 3 .7 .09 inches for y bar.
00:39
Now for the moment of inertia around the neutral axis it is 145 .98 inches to the power fold.
00:57
I have defined the q for point a and q for point b.
01:07
Qa is y bar.
01:09
A, adad, and for qb is y bar b dad, aad.
01:18
So for y bar a dad, it is this level, and y bar b that it is this level.
01:34
And this is the add for qa...
