We need to find out the shear force bending moment diagram for this particular question.
00:07
Now first of all we will try to learn this is called the hinge support and this is normal support reaction support so first of all we will try to make the free body diagram of this particular fusion okay now see just take this way this is the support okay now for this support just this is a point so just imagine a reaction force is applying here and another for this supports a another reaction force rb is applying here because this is the hinge on and this can move around this point okay means this can move there will be another reaction point in x direction as well as y direction just imagine this is in y direction there is in x direction this is your point c okay and because this is what this is we call the load okay weighted load now this will this is applying up to two meters and everywhere is 20 kilo newton per meters so total load will be seen this is in 20 kilo newton per meter now if we will multiply when two meter so it will meter to meter will get cancelled and we will find out 40 kilo newton okay so we can apply here 40 kilo newton this is over free -go -dial dialogue so first of all to solve this question we will move one by one take in at direction there is equilibrium force okay in x direction means in this direction so in this direction fx equals to zero if we will tell you then we will see only one force is applying over there r b x and the value of this is equal to zero because in this direction there is no any force except this one we will consider ef y means in y direction means in this direction or in this direction then we will see 40 kilo newton is applying in this direction and ra this r a plus r b y will balance this 40 kiloons isn't it okay so this will be close to 40 kilo so now first of all we will see bending women in this direction okay at which point at b point okay now we will go one by one so first of all if we will take a point where we can take this point because around this, this will round like this.
03:23
So bending moment at point zero.
03:26
Bending moment means force into perpendicular distance.
03:31
Okay.
03:32
Now for this point, this force is applying 40 kilo.
03:38
So 40 kilo newton into total distance this is 2 and this is 1.
03:43
2 plus 2, 4 plus 1, 5.
03:48
And in this direction in upper side, it is applying so there will be minus side.
03:54
So, ra into it is applying 2 into 4 meter equals to 0.
04:01
Now from here we will find out value of ra will be 14 into 5 divided by 4...
