3 Column AB carries a centric load P of magnitude 15 kips. Cables BC and BD are taut and prevent motion of point B in the xz plane.Using Euler's formula and a factor safety of 2.2 and neglecting the tension in the cables, determine the maximum allowable length L.Use E = 29 × 106 psi. (Round the final answer to one decimal place.)LPBW10 x 22DThe maximum allowable length L isft.

250 mm A D P = 25 kN B 30 60 C TOP VIEW 280 mm Member AD is fabricated by joining two bars (E=205GPA, G,A=82GPA) and is pinned to plate ABC using a 5 mm diameter pins as shown in the figure. The yield strength of the pins is T,=890MPA. Plate ABC is a right triangle and is fixed along its edge BC. A 25KN Force P is then applied at end D causing a lateral strain in member AD with magnitude equal to 7.5x104mm/mm. This also causes Point A to displace only along the horizontal resulting to a shear strain at point A equal to y,=+0.00165rad. Determine the following: 1. Poisson's ratio of material used in member AD, vD 2. The normal strain in member AD, CAD 3. The average stress experienced by pin A, TA 4. Factor of Safety of pin A with respect to yielding, FS,A 5.
