Hello students, to determine the deflection at a point c on the beam ab.
00:07
So let's take the point c here.
00:10
So we are given that the modulus of elasticity is equal to 1 .5 times 10 to the power minus 10 to the power 3 ksi.
00:18
So 1 ksi is equal to 6 .89476 mega pascal.
00:25
So that will give us 10 .34214 mega pascal total elasticity modulus of elasticity.
00:35
Now let's apply a load of 1 kilo newton at point c.
00:42
Okay, so that is the 1 kilo newton at point c.
00:45
So in this game, in this case, the beam will have a deflection due to that load applied.
00:50
So that is equal to delta c.
00:54
So delta c will be acting in this point.
00:57
So if you apply, let's apply 1 kilo newton at a and that the c be displaced into a place which is much more.
01:10
So this is at the length to be equal to 10 meters and this length c be at 3 meters.
01:18
Okay, now the deflection that supply 1 kilo newton force at here.
01:25
So the deflection will be represented from the center of mass.
01:31
So center of mass is starting from 5.
01:32
So the deflection, the force acting will be equal to 1 kilo newton times 5.
01:38
That will be the total force acting in the this direction.
01:43
So the balancing force will act here.
01:45
So that will be equal to 1 balancing force...
