Determine the magnitude of the two smallest horizontal forces that are equivalent to m if they're applied at the corners a and corner d.
00:10
So here i've just drawn a little diagram, and if your numbers are different for the inches, just please feel free to change them to match your problem.
00:18
So when it's acting at a and d, our couple c is equal to row .d.
00:27
So we set our 10 pound feet equal to a row in pounds times 10 times one half, which is pound per inch.
00:38
So row is equal to 12 pounds.
00:41
And so that is going to be the magnitudes of the two forces.
00:46
What about at the corners b and c? if we take a look at our corners b and c, our diagram can look something like this.
00:54
Here's eight inches, eight inches, here's a and b and b and c.
01:03
This is eight inches and this is two inches...
