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 boom of the wall crane 4m long is held at right angles to the wall by a wire that is attached to the wall 3m above the foot of the boom. If the load lifted is 45000N, find the tension in the wire and the compression force in the boom. Neglect the weight of the boom. Draw a FBD

A woman who weighs 4.92E+2 N is leaning against a smooth vertical wall, as the drawing below shows. As shown, h1 = 1.19 m, h2 = 0.420 m and θ = 59.5°. Calculate the force FN (directed perpendicular to the wall) exerted on her shoulders by the wall.
Question 2) The figure shows a mechanical model of the Russel fracture traction device and the leg. The leg is held in balance in the position indicated by the two weights attached to the two cables. The combined weight of the leg and the cast is W=210 N. The horizontal distance between points A and B where the cables are attached to the leg is L=100 cm and the vertical distance is d=6 cm. Point C is the center of gravity of the cast and leg at three quarters of the L measured from point A (3L/4= 75 cm). The angle that cable 2 makes with the horizontal is measured as β=33°. Accordingly, in order for the leg to remain in balance in the shown position; a) Find the tensile force T1 in cable 1. (Write your result in N) b) Find the tensile force T2 in cable 2. (Write your result in N) c) Find the angle α of cable 1 with the horizontal. Response
