1. Determine the geometry of each fence element (lengths and
angles)
2. Determine the axial force of each element and identify if it
is in tension or compression (present diagram)
3. Assuming rectangular shape height =H and width =H/2 determine
the dimensions of each element if allowable stress
σ albw=205KPa
4. If the connection between elements is "pin", determine the
minimum diameter (d) if the Shear Allowable T
4.35X 10^8 kPa and number of pins needed
5. Determine the maximum load P that the truss can resist
without causing it to buckle. the LI member. Use A-36 steel.
6. The stress state at a point in the truss is shown in the
figure. determine in member LI, a) the principal stresses and b)
the maximum shear stress in the plane, and the average normal
stress at the point. Specify, in each case, the orientation of the
element.
7. Determine the vertical deflection in length LI of the
truss.
