List of top Structural Engineering Questions on Analysis of trusses asked in GATE CE

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.
