The Formula for crushing load p=π^2EI/L^2.
He given that beam with one end is fixed and the other end is hinged then we consider L=L/√2 sub this in above formula you can get c=1/2.

Pai^2EI/(l/root 2)^2 = pai^2EI/cl^2,
Cl^2= l^2/2,
2c=1,
C=1/2,
So the answer is right.
Cl^2= l^2/2,
2c=1,
C=1/2,
So the answer is right.

The valve of C should be 1/root 2. We can not relate square of L with C, these both are separate.

Value of C = The number multiplied with l2 but not the equivalent length. Equivalent length in this case is l/Root over 2. That means L2= (l/1.414) to the power of 2. That means l2/2.
Now the multiplication number for l2 is 1/2. Hence Answer is 1/2 correct.
Now the multiplication number for l2 is 1/2. Hence Answer is 1/2 correct.
