Determine the forces in the rods if a turn buckle and rod ef undergoes one full turn.
00:06
So let's write our given variables.
00:09
We're given our length is 0 .75 meters.
00:13
B is 0 .5 meters.
00:16
Our area is 125 millimeters squared.
00:20
Delta l is 1 .5 millimeters.
00:23
And e is 200 gpa.
00:27
So in equilibrium, the sum of the moments of the moment's about point e, which if we draw our diagram, should look something like this, this is our point e, this should be equal to zero in equilibrium.
00:42
So we have the tension of cd times b, plus the tension of ab times b is equal to zero.
00:52
And so we see tension cd is equal to tension ab.
00:56
Now the sum of all the forces in our y direction is equal to zero.
01:01
So from this, we get t -a -b plus t -c -d minus t -e -f is equal to zero...
