So in this problem they want us to draw the free body diagram of the beam.
00:07
So we draw the beam, let's draw the beam right here.
00:12
Let's draw the beam right here.
00:14
We can see that here at the right we're going to have the reactions on this wall here.
00:21
Because it's fixed to the wall, we're going to have a positive.
00:27
Let's call it r -x, r -y.
00:30
We're going to have an rx and we're going to have a moment moment at the they say at the reaction at the point of reaction so additional to that we have this force of 20 kiloons right here 20 kiloons at a at a distance of 12 meters and this this force right here this spread out force right here we can either put it as a single force in the exact middle between it, which is going to be a 7 .5 meters, we can leave it like that.
01:10
So i would replace it with the equivalent, which is going to be 15 kiloons, multiplied by a longitude here, a length of 5...
