Web2 days ago · The Sunday gospel lectionary reading for the Second Sunday in Easter is John 20.19–31, which includes Jesus’ encounter with so-called ‘doubting Thomas’. It is the set reading for this week in all three years of the lectionary, so we know it well—and need to reflect on it if we are going to preach effectively on this well-trodden ground. Web15 Jul 2024 · Second moment of Area/ Torsional constants are calculated with respect of a given axis and if the axis changes, these parameters should change. I dont understand why these parameters are not changing. I intend to place my sketch of cross section about desired axes so that they parameters are calculated with respect to that axis.

Web1 Sep 2024 · The second moment of area is not to be confused with mass moment of inertia. The area moment of inertia is used to characterize the resistance offered by a body (such as a beam) for deflection under load. WebFor a 2D object with density ρ ( r), the second moment of area is A = ∬ r 2 d r and the moment of inertia is I = ∬ ρ ( r) r 2 d r. When ρ ( r) = ρ 0 you get I = ρ 0 A and when ρ 0 = 1 you get equality. Otherwise, they are not necessarily the same.
