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  

1 - wave length

2 - amplitude

3 - crest

4 - trough
