Q. For a truss with a total load of 12 kN applied at joint C, what is the force in member AC if the truss is in equilibrium?
A.
6 kN
B.
12 kN
C.
0 kN
D.
8 kN
Solution
In a statically determinate truss, the force in member AC can be determined using the method of joints. If joint C has a load of 12 kN, member AC will carry the same load in equilibrium.
Q. In a beam subjected to bending, what is the relationship between the bending moment and the curvature?
A.
M = EI * ρ
B.
M = ρ / EI
C.
M = E * I * ρ
D.
M = ρ / E
Solution
The relationship between the bending moment (M) and the curvature (ρ) in a beam is given by M = EI * ρ, where E is the modulus of elasticity and I is the moment of inertia.
Q. In a frame structure, what is the primary factor that affects its stability?
A.
Material properties
B.
Geometry of the frame
C.
Load conditions
D.
All of the above
Solution
The stability of a frame structure is affected by material properties, geometry of the frame, and load conditions, making all of the above factors important.
Q. In a statically indeterminate beam, if the support reactions are not sufficient to maintain equilibrium, what method can be used to analyze the structure?
A.
Method of Joints
B.
Method of Sections
C.
Superposition
D.
Stiffness Method
Solution
The stiffness method is commonly used to analyze statically indeterminate structures by considering the stiffness of members and the compatibility of deformations.
