In this question, we have to construct a graph to show the relationship of the force ab and force b .c as a function of p.
00:15
So from the diagram in the textbook, we will have that if ab plus fbc they are equal to p.
00:29
We give this equation, equation 1.
00:31
And from the elastic behavior, the sum of the subtraction of delta c minus del c, it has to be equal to zero.
00:47
So del c is the displacement from the force p, that is p, time the length of the rod, time the area, time e, minus del c.
01:06
Is from the internal load of l or a .e and from a at 4, nudge, fbc from a equal to 1, thumb e.
01:35
And we'll have that.
01:37
Fbc is 0 .9231 p and if ab will be 07692p.

Give this second and the third equation...
