The displacement for B is 0.03161+0.0016858=0.0332958, not 0.033468.

Thank you for the great video! I believe the last calculation adds the displacement at E and the stretch of EB. It should be .0016858+.03161=.0332858, slightly different from video

This is presented so beautifully, thank you so much! God bless you.

Thank you for this excellent explanation.
You're better than my college teacher.

To find the Y which is the displacement of E. I think you forgot sir to convert the 8 ft and 2 ft to inches. Because the results of delta's EB and CF are in inches. But you've use 10' and 2' for the similar triangle.

Would the weight of the members be relevant in a real-world application or are they small enough that they are negligible?

[mwenge]

Why are we adding displacement of e and the stretch of the member to find displacement of b? And what's the difference between the stretching of a member and a point?

Someone please respond quick. My exam is tomorrow😭😭

[amolsandbhor]

for calculation 12.5 mm radius should converted into inches 0.4921 inch= 12.5mm

[ashar]

Isn't y the change in height of eb? so isnt it the same as δeb? why are the values for δeb and y different?

[stevemaldonadomelendez]

Shouldn't the members FC & BE be in compression? Just a little confused on why they are stretching.
