Euler's formula holds good only for long columns.
It is applicable when a column is slender and its failure is due to buckling, not material strength.
For short columns, failure usually occurs due to compressive stress, not buckling, so Euler's formula is invalid.

Euler's formula gives correct results only for very long columns.
For short or long columns Rankine's Formula is used.
Load columns can be analysed with Euler's column formulas can be given as;
P = n 2 π 2 E I L 2.

Euler's formula gives the relation between bending and crushing when short columns the bending stress is low as compared to crushing stress. In the long column, the bending and crushing are relatively equal to each other.

In order to make the calculation of stresses due to torsion easy, why do we have to make the assumption that plane sections plane? Please clear me.

Slenderness ratio is the ratio of effective length to least radius of gyration.
Least radius of gyration is from,
I = Ak^2.
Where, I is least moment of inertia I.e., minimum of Ixx or Iyy.
