A vertical bar consists of three prismatic segments A1, A2, and A3 with cross-sectional areas of 6000 mm2 , 5000 mm2 , and 4000 mm2 , respectively. The bar is made of steel with E 5 200 GPa. Calculate the displacements at points B, D

Answer and Explanation:

For computing the displacement at point B and D we need to determine the following calculations

= 250 + 350 - 50

= 550 N

Now the deflection for bar AB is

Now for bar BC it is

And for bar CD it is

Now the displacement is as follows

For B

2.292 × 10^{-4} mm

For D, it is

We simply applied the above formulas for determining the  displacements at points B, D and the same is to be considered  

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
