tigerstyle said:but what about the side DE and AB because they are at an angle 120 degree. or do i use sin rule at the centroid of DE to find the height?
Thanks
rock.freak667 said:What distance did you use for side AB and DE?
tigerstyle said:I used sin rule to calculate it and it came as 0.866m.
rock.freak667 said:0.866 m would be the height of triangle formed, you didn't account for the centroid being halfway down the rectangle.
tigerstyle said:what i did for rectangle DE and AB: the midpoint will be 0.5m. and then drew a triangle and used sin rule to find the height of centroid vertically. is that right?
tigerstyle said:I have got the centroid and the second moment for this problem. and have found the shear flow in the walls. now the question is asking me to evaluate the shear force in the walls. i don't know what that means. can you help please
thanks
rock.freak667 said:How did you calculate the shear flow? Shear flow is related to the shear force, first moment of area and second moment of area.

Can you please help me?
A thin-walled beam is a type of beam that has a small cross-sectional area compared to its length. This results in a high ratio of length to cross-sectional area, making it more vulnerable to bending and buckling.
Thin-walled beams are commonly used in the construction of lightweight structures, such as aircraft wings, bridges, and cranes. They are also used in the automotive, aerospace, and marine industries.
The main difference between a thin-walled beam and a solid beam is their cross-sectional area. A thin-walled beam has a small cross-sectional area, while a solid beam has a larger cross-sectional area. This results in different stress and deformation behaviors under loading.
Studying thin-walled beams is important for understanding the behavior of lightweight structures and ensuring their safety and stability. It also allows engineers to optimize the design and material selection for these structures, resulting in cost-effective and efficient solutions.
The main challenge in analyzing thin-walled beams is their complex stress distribution and behavior under loading. This requires advanced mathematical models and numerical methods for accurate analysis. Additionally, the material properties and manufacturing processes of thin-walled beams can also affect their behavior, making analysis and design more challenging.
