Determine the fixity constant “k” for columns 2 and 3 shown in the figure below. Columns are 450mm x450mm and the beams are 300mm x600mm.

1. The figure below shows a roof canopy beam which is supported by a φ20 mm hanger rod. The roof beam is a W200×19 steel beam with a cross-sectional area A = 2480 mm2, section modulus, Sx = 163×103 mm3 and a moment of inertia Ix = 16.6×106 mm4. The modulus of elasticity for steel is 200 000 MPa.  1)     Determine the beam reactions at A and B.      2)     Determine the axial stress in the 20 mm hanger rod and in the W200x19 beam.     3)     Determine the shear force and bending moment   at the midspan of the beam     4)     Determine the bending stress in the beam at the mid-span of the beam.

The maximum vertical deflection of W8x15 beam subjected to the loads shown in the figure below is closest to which of the following deflection limits: Group of answer choices L/180 L/480 L/270 L/360

The two mooring cables exert forces on the stern of a ship as shown. Represent each force as a cartesian vector and determine the magnitude and coordinate direction angles of the resultant.
