Terminology - Second moment of area
Terminology - Second moment of area
(OP)
Hi all,
Where I went to school we used a quantity called second moment of area to give us information about a sections profile for bending calculations. (=BD³/12 for rectangular sections).
The people who wrote Pro E however, must have gone to a different school as this quantity is not displayeed in their section properties.
Is that what the Area moment of inertia is?
Cheers
Hayden

Yep, that's the one.
The "moment of inertia" and "second moment of area" are one in the same thing. Most textbooks I have seen use the term "moment of inertia" more often.

I'm from New Zealand and now living in the UK. Here they call it second moment of area too.

Setup --> units. From here you are able to set the units for each type of measurment. Now recalculate the model analysis and you will see the units that you are familiar with using.
