Young modulus

I have a project to measure young modulus by measuring the deflection of a beam under point mass. I have derived the equation but i am confused to how the end of beam should be placed to obtained best precision. Should it be both clamped end, freely supported end or a mixture of both?

My idea so far is that for both freely supported ends, its disadvantage is the reference point of x=0 might be displaced during deflecton. However, i can't think of the both clamped scenario disadvantages

By clamped and do mean fixed end? By such test useally the and is free (support doesnt take any banding moments). Teoretecly u can support your beam as you want. You will have differnet stresses and different deflections.
