QUESTION: 1

### A simply supported truss shown in the given figure carries load as shown. The force in member BE is

Solution:

At joint D, there is no external force so force in FD and BD is zero.
Taking moment about A, the reaction at B,

Considering joint B, force in member BF,

force in member BE,
FBE=1t (tensile)

QUESTION: 2

Solution:
QUESTION: 3

### The force in member FD in the given figure is

Solution:

Considering joint equilibrium at D. The force equilibrium equation in vertical direction gives FD = 50 kN tensile

QUESTION: 4

In the cantilever truss shown in the given figure. the reaction at A is

Solution:

Only a horizontal reaction can exist at A.

HA x 5 = 10 x 15
HA = 30t

QUESTION: 5

Force in the member BC of the truss shown in the given figure is

Solution:

By considering joint equilibrium at B,

QUESTION: 6

A simply supported truss shown in the given figure carries a load of 20 kN at F the forces in the members EFand BE are respectively:

Solution:

Force in EF is zero if joint equilibrium at E is considered force in SE will be tensile, and its value will be 10 kN by considering joint equilibrium at B.

QUESTION: 7

Axial force in the member BC of the truss shown in the given figure is (where α = 30°)

Solution:

The given truss is symmetrical. So force in member BO and EO will be same in magnitude and nature both. Joint equilibrium at O.

QUESTION: 8

Axial forces in the members 1-2 and 1 - 5 of the truss shown in the given figure .are respectively

Solution:

Cutting a section through 1-2; 2-5; and 5-6. Taking moment of left part about 5,

Cut a section through 1-2, 1-5 and 4-5 and balance vertical force for left part only,

QUESTION: 9

A pin-jointed tower truss is loaded as shown in the below figure. The force induced in the member DF is

Solution:

Cutting a section through AC, CD and DF and taking moment of upper portion about C.The forces in the members AC and CD meet at C so they do not produce any moment. The force in member DF,

QUESTION: 10

For the truss shown in the figure, which one of the following members has zero force induced in it?

Solution:
