    Professor, when you take 8kNs for the calculation of elongation in A isn't there a (4+4) compression also acting there? total of forces going to the right (tension) is 10kNs and the total of forces going to the left (compression) is 10kNs. Is this how to calculate the total forces P in the points or am I wrong somewhere?

    Why we did not take these 2kN's for calculation? I am confused. If anyone knows the answer, pls reply it.Thank you!!

    Hi, you can use axial load diagram to solve this even faster. You can take load at A as 8kn, load at B as 4kn, load at C as 6 kn and load at D as 2kn. Assume load going left as positive and loads moving right as negative. Axial load diagram would be as follows: +8kn. 8-4=4kn. 4-6=-2kn A. B. C. D When the -2kn reaches point D, it meets the left side moving load of 2kn. -2+2=0 Since there is no load as I explained above after point D, you do not need to calculate anything. If you still did not understand, let me know you email and o will send you a solution of this problem.

    Hi. He looks at one side of each section as we know it is in equilibrium. Forces will be equal on both sides of the imaginary midpoint squiggle he drew. On his first section he looked at (8kN) he looked at the left side as it was more simple. He then showed adding the right side did also equal 8kN to show this. I was confused at first also.
