The attached picture shows a double symmetrical bowl-like cross-section. The equation of the curved part in the positive quarter of the coordinate system (black arc in the picture) is y (z) = Jim/z a; y 2 0 A z 3: a, where K is the factor considering the unit, the square root of the meter 1c : \\lm. Calculate the second moment of area of the cross-section with respect to the z- axis with the given numerical a-measurement. Dimension a is 0.5 m. Instructions: First divide the cross-section into suitable parts. You can use the following steps for parts of the cross-section and for the whole cross-section: a) Solve for the dimension b of the figure. {1 p.) b) Solve for the required surface areas. (1 p.) c) Solve for the second moment of area of the cross section. (3 p.)
