plot the 2D curve that is a solution to a nonlinear equation

I want to find the dimensions of a beam with a rectangular cross section

that has equal torsional and bending stifnesses. The bending stiffness is and the torsional stiffness is . Where

• 
• 
• 

the equation can be expnaded to the nonlinear polinomial equation:

now assuming ν is 0.275, I want to find all the [h, w] points or curves satifying the above equation in [0, 2] and [0, 50] range for h and w respectively.
