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. Displacement of point D, A,
The steel truss (E =200 GPa) shown in figure below has a cross-sectional area of 1920 mm².
Determine:
a. The largest allowable load F if the change in length of member BD is not to exceed 1.6 mm and a factor
of safety of 2.5.
b. The displacement of support D due to the load calculated in part a.
