if we will use the proper calculation of the bending moment
and where the sagging is more according to the material
before load is added.

if after putting support at the end point in the prototype

sagging takes place , a third support is added.

again, if sagging takes place two more supports are added
one one each sag points

therefore total of 5 supports.

i guess..

is it right ??

if anyone can tell me?
