Beam analysis

Question 1

What is the moment of inertia equation for a rectangle in x direction?

Answer 1

Ix = breadth * height^3 / 12

Question 2

What is the moment of inertia for a triangular beam?

Answer 2

I = 1/36 * breadth * height^3

Question 3

What is the moment of inertia equation for a rectangle in y direction?

Answer 3

Iy = 1/12 * height * breadth^3

Question 4

What is the moment of inertia equation for a circular beam?

Answer 4

I = 1/4 * pi * r^4

Question 5

What is the normal stress due to bending in a beam?

Answer 5

Stress = Moment * vertical distance from center (y) / moment of inertia
