How come the value of x in
How come the value of x in finding the deflection under the 500N load is the same? shouldn't x=4 for the EIy due to 800N load?

In reply to How come the value of x in by Hi (not verified)
x is the location where your are solving for the deflection. You are referring to the location of the load. The location of the load is not necessarily the location of the deflection you wish to calculate.
x=2 is the location of the 500 N force to cause a deflection at x=2 also.
x=4 is the location of the 800 N force, while x=2 is the location of the deflection caused by the force. Notice that the location of the force is not the same as the location of the deflection.

Sir what if we want to find EI at midpoint? Do we just substitute x=2.5 in the equation?
Yes.

Yes. But there is another way, a better way I suppose, to calculate midspan deflections. Check it from here: https://mathalino.com/node/955.
Use x=2.5 from here and compare it to the results you've got from the Midspan Deflection link.
