Mechanical Engineering Discussions / Bernoulli-Euler’s elastic curve equation
« Last post by admin1 on December 20, 2016, 03:15:34 AM »
Bernoulli-Euler’s elastic curve equation
EI (d2y/dx2)=M

Where E is modulus of elasticity which is of constant value.
I is moment of inertia (for a rectangular cross section beam, bh3/12; b=width of beam, h=height of beam).
M=moment developed.
