Work 3
Topic: Calculation of geometric characterizations of plane cross - section
Objective: to acquire skills of theoretical calculation of geometric characterizations of plane cross - section
Task: For the given composed cross-section it is necessary:
1. The given cross-section in a certain scale is draw. All sizes in numbers and all axes must be specify;
2. Define the position of centroid of given cross-section;
3. Calculate the central moments of inertia;
4. Find direction of principal central axes of inertia;
5. Define the principal moments for given section.
Methodic guidelines:
Let see lecture 5 - 6. In running this work, the student should use the sample contained in the file MOD_3_pdf
The scheme of the task is given by the teacher at the lesson in the classroom, or it can be obtained from the file PR_5.pdf.
The student must take the task scheme according to its number in the list of the group journal.
Please, send a file named MOD_3. doc. (or in the form of a photo of the work),
in MS Word format, for cheking by the Elearn system.
Assessment criteria:
The estimation of each of task point - 5 points.
In total - 25 points.
