Question 1 Calculate the principal second moments of area, I, and I., for the following cross section. The position of the centroid is at y'= 36.4 mm and z' = 26.4 mm, relative to the bottom left corner. All dimensions are in mm. 120 100 10

Locate the centroid y of the composite area. Express your answer to three significant figures and include the appropriate units. j = 3.79 in Submit Previous Answers Correct Figure < 1 of 1 Part B Determine the moment of intertia of this area about the centroidal a' axis. Express your answer to three significant figures and include the appropriate units. 3 in. I = 198 in 5 in. 1 in. 1 in. Previous Answers Submit 2 in. v Correct - 3 in.-3 in.- Correct answer is shown. Your answer was either rounded differently or used a different number of significant figures than required for this part.

Compute the coordinates of the centroid (, y) of the area shown. Also compute the area moment of intertia about the x' axis that passes through the centroid. 2013 Michael Swanbom BY NC SA d C Ka*b*c Values for dimensions on the figure are given in the following table. Note the figure may not be to scale. Variable Value а 33 mm 19 mm 17 mm d 68 mm The x coordinate of the centroid is a = mm. The y coordinate of the centroid is y mm. The moment of inertia about the x' axis going through the centroid is Iæ' mm4.
