In the figure below, the 1300-kg uniform bar AB is suspended from two cables AC and BD each with a cross-sectional area of 410mm². The stresses in AC and BD are limited to 110MPa and 53MPa, respectively. D 1.7m 1.7m -x-P B 3.5m Find the location x of the largest additional vertical force that can be applied to the bar. meters in 2 decimal places

A steel strut S serving as a brace for a boat hoist transmits a compressive force P= 57 kN to the deck of a pier as shown in the figure. The strut has a hollow square cross section with wall thickness t = 9 mm and the angle O between the strut and the horizontal is 30°. A pin through the strut transmits the compressive force from the strut to two gussets G that are welded to the base plate B. Four anchor bolts fasten the base plate to the deck. The diameter of the pin is dpin = 16 mm, the thickness of the gussets is tG = 14 mm, the thickness of the base plate is tg = 10 mm, and the diameter of the anchor bolts is dpolt = 10 mm. Determine the bearing stress between the anchor bolts and the base plate in MPa. ROUND OFF TO TWO DECIMAL PLACES. Pin S 16 (a) (b)

The initial compressive force of a steel column can be determined by Euler's buckling formula. The column has the following properties: A = 9484 mm2 Fy = 345 MPa Ix = 164 x 106 mm4 ly = 23 x 106 mm4 E = 200 GPa Proportional limit, f = 290 MPa %3D %3D The x-axis has an unbraced length of 10 m which is pinned athe top and fixed at the bottom with an k = 0.70. The y-axis has unbraced length of 5 m due to the bracing at the mid-height. Determine the factor of safety for the load shown with respect to buckling in the plane of the figure.
