List of top Structural Engineering Questions on Analysis of trusses

The plane truss shown in the figure has 13 joints and 22 members. The truss is made of a homogeneous, prismatic, linearly elastic material. All members have identical axial rigidity. A to M indicate the joints of the truss. The truss has pin supports at joints A and L and roller support at joint K. The truss is subjected to a 10 kN vertically downward force at joint H and a 10 kN horizontal force in the rightward direction at joint B as shown.

The magnitude of the reaction (in kN) at the pin support Lis (rounded off to 1 decimal place).

The plane truss shown in the figure is subjected to an external force \( P \). It is given that \( P = 70 \, \text{kN} \), \( a = 2 \, \text{m} \), and \( b = 3 \, \text{m} \). 

The magnitude (absolute value) of force in member EF is \(\underline{\hspace{1cm}}\) (round off to the nearest integer).

Refer the truss as shown in the figure (not to scale). 

\( \text{If load, } F = 10\sqrt{3} \, \text{kN}, \, \text{moment of inertia} \, I = 8.33 \times 10^6 \, \text{mm}^4, \, \text{area of cross-section} \, A = 10^4 \, \text{mm}^2, \, \text{and length} \, L = 2 \, \text{m} \text{ for all the members of the truss, the compressive stress (in kN/m}^2 \text{, in integer) carried by the member Q-R is \(\underline{\hspace{1cm}}\)}. \)

A truss EFGH is shown in the figure, in which all the members have the same axial rigidity \( R \). In the figure, \( P \) is the magnitude of external horizontal forces acting at joints F and G.
