Structural Analysis online quiz on “Qualitative Influence Lines For Frames”.
1. Force-displacement requirements are not necessary to be satisfied for statically indeterminate structures.
State whether the above statement is true or false.
a) true
b) false
Answer: b
Clarification: Force-displacement requirement along with equilibrium and compatibility conditions are required to satisfy for a statically indeterminate structure.
2. Force-displacement requirement of statically indeterminate structures depend upon which factor?
a) material’s response
b) magnitude of load applied
c) supports
d) position of load applied
Answer: a
Clarification: It depends upon material’s response. We have assumed the material to linear elastic for further discussions.
3. Who of the following initially developed force method?
a) Muller
b) Breslau
c) Mohr
d) James clerk Maxwell
Answer: d
Clarification: Maxwell originally developed force method. Later options then developed this method.
4. Which of the following conditions form the basis of this method?
a) equilibrium conditions
b) force-displacement conditions
c) load applied
d) compatibility conditions
Answer: d
Clarification: This method is based on compatibility conditions and therefore it is also known as compatibility method.
5. Redundant forces are calculated in last step while using force method.
State whether the above statement is true or false.
a) true
b) false
Answer: b
Clarification: Redundant forces are calculated in initial steps in this method. Rest of forces is calculated by using these values.
6. Which of the following conditions form the basis of displacement method?
a) equilibrium conditions
b) force-displacement conditions
c) load applied
d) compatibility conditions
Answer: b
Clarification: Force displacement relations are written in the first step of displacement method.
7. Which of the following conditions is used in both force and displacement method in any stage?
a) equilibrium conditions
b) force-displacement conditions
c) load applied
d) compatibility conditions
Answer: b
Clarification: Force displacement equations are used in both methods.
8. Flexibility coefficients are used in which of the following method?
a) force method
b) displacement method
c) both force and displacement method
d) virtual force method
Answer: a
Clarification: Coefficient of unknowns while using force method is known as Flexibility coefficients.
9. Stiffness coefficients are used in which of the following method?
a) force method
b) displacement method
c) both force and displacement method
d) virtual force method
Answer: b
Clarification: Coefficient of unknowns while using displacement method is known as stiffness coefficients.
