**Evaluation of Moments of Inertia Application Center**

7/10/2012 · Here's a simple way to calculate the moment of inertia of a triangle. I start with the moment of inertia of a rectangle and show how to add up a bunch of very thin rectangles (integration) in... Integrate to derive a formula for the moment of inertia for a general triangle. Note the dy is assigned the value 1 so that the Maple integrator does not confuse it as a mathematical variable.

**Moment of Inertia of an Equilateral Triangular Plate**

For each triangle and square, use the parallel axis technique to calculate the total moment of the subshape around the origin, namely (centroid distance from origin)^2*area + moment. Add this up for each trapezoid, and you will get the correct moment for the entire polygon.... Calculate the 2nd moment of area for each element about the reference axes. Multiply the Area of each element by the square of the distance from the centroid of each element to the centroid of the cross-section(x1 and y1). 8. Calculate moments of Inertia of each element about it’s own centroid. Check the basic shapes at the bottom of poster for help. 9. Calculate Ix and Iy. Do this by adding

## How To Find Area Moment Of Inertia Of Triangle

### where I' is the moment of inertia in respect to an arbitrary axis, I the moment of inertia in respect to a centroidal axis, parallel to the first one, d the distance between the two parallel axes and A the area of the shape (=bh/2 in case of a triangle).

- where I' is the moment of inertia in respect to an arbitrary axis, I the moment of inertia in respect to a centroidal axis, parallel to the first one, d the distance between the two parallel axes and A the area of the shape (=bh/2 in case of a triangle).
- The area moment of inertia of triangle is the product of width and cube of the height divided by 36. The formula to find second moment of inertia circle and semicircle is provided in the area moment of inertia …
- Integrate to derive a formula for the moment of inertia for a general triangle. Note the dy is assigned the value 1 so that the Maple integrator does not confuse it as a mathematical variable.
- Using the limits of x to be 0 to h, and the limits of y to be -xtan30 and +xtan30, you get the moment of inertia about an apex to be 0.32075h^4M/AL, where h is the height of the triangle and L is the area. Using the parallel axis theorem, you can find the moment of inertia about the center by subtracting Mr^2, where r is 2/3h. The final result is ML^2/12.
