- Note: End of the question answer also given if you got answer other than that values please leave it. Two long poles each 5.0 m tall, one of steel and one of hardwood (such as oak), are anchored vertically in a concrete slab so that only that part above the concrete can bend or be compressed. If the top of each is connect to the ground by a wire under tension to a point 1.0 m from its base, by how much does each bend and is compressed by this wire if it has a tension of 10,000 N. Assume that each pole has a radius of 6.0 cm. Answers: Δxwood = 87 μm, ΔLwood = 290 μmFor the beam l-section below, calculate the second moment of area about its centroidal x-axis (Ixxcentroid), where b1 = 10.50 mm, b2 = 2.50 mm, b3 = 38.50 mm, d1 = 1.50 mm, d2 = 36.50 mm and d3 = 12.50 mm. %3D Give your answer in mm4 to two decimal places. b1 d2 -+ b2 d3 b3The properties of the unequal angle section are Ix=80.9in.4,Iy=38.8in.4, and Iu=21.3in.4. Determine Ixy.
- Determine Iu for the inverted T-section shown. Note that the section is symmetric about the y-axis.Figure (a) shows the cross section of a column that uses a structural shape known as W867 (wide-flange beam, nominally 8 in. deep, weighing 67 lb/ft). The American Institute of Steel Construction Structural Steel Handbook lists the following cross-sectional properties: A=19.7in.2,Ix=272in.4, and Iy=88.6in.4. Determine the dimensions of the rectangle in Fig. (b) that has the same Ix and Iy as a W867 section.The cross sectional dimensions of a beam are shown. If the flange thickness, h, is 12.5 mm, determine the vertical distance from the bottom edge of the flange to the centroid of the cross section. Note: State your answer in mm Note: Do NOT include units in your answer. Answer: ISO HH (20 m
