Test: Determinacy And Stability - Question 3

 If Y > 3X (X and Y are from the above question) then, the system is:-

Detailed Solution for Test: Determinacy And Stability - Question 3

Answer: a
Explanation: As there can be at max. 3X equations, at least one of the forces will be unsolvbale.

Test: Determinacy And Stability - Question 4

 If in a planar system, only 2 reaction forces are acting, then the system is:-

Detailed Solution for Test: Determinacy And Stability - Question 4

Answer: a
Explanation: If no. of reactions is less than 3 in any planar system, then the system is essentially unstable.

Test: Determinacy And Stability - Question 5

If all the reactions acting on a planar system are concurrent in nature, then the system is:-

Detailed Solution for Test: Determinacy And Stability - Question 5

Answer: c
Explanation: The system can rotate about the point of concurrency. So, it is essentially unstable.

Test: Determinacy And Stability - Question 6

 If 4 reactions are acting on a beam, then the system is:-

Detailed Solution for Test: Determinacy And Stability - Question 6

Answer: d
Explanation: 4 reactions mean that the system is definitely indeterminate. But stability would depend upon the nature of forces acting on the planar structure.

Test: Determinacy And Stability - Question 7

If a system has more equations of equilibrium than no. of forces, then the system is:-

Detailed Solution for Test: Determinacy And Stability - Question 7

Answer: b
Explanation: In these cases, system is unstable and unsolvable and is termed as partially constrained.

Test: Determinacy And Stability - Question 8

How many cases out of the following are improperly constrained?Parallel forces, concurrent forces, perpendicular forces, only moment

Detailed Solution for Test: Determinacy And Stability - Question 8

Answer: b
Explanation: parallel and concurrent are improperly constrained.

Test: Determinacy And Stability - Question 9

If a structure has total 10 joints, then what should be the minimum no. of joints in which equilibrium equations should be concurrently satisfied for stability?

Detailed Solution for Test: Determinacy And Stability - Question 9

Answer: d
Explanation: For stability, equilibrium equations should be satisfied concurrently at each and every joint of the structure.

Test: Determinacy And Stability - Question 10

In the following questions, j represent no. of joints and r represents no. of external forces.10. If a structure has 2j – r no. of members, then it will be:-

Detailed Solution for Test: Determinacy And Stability - Question 10

Answer: c
Explanation: In these cases, structures can be stable as well unstable.

Test: Determinacy And Stability - Question 11

If a truss consists of a non-triangular element, then it will essentially be unstable.
State whether the above statement is true or false.

Detailed Solution for Test: Determinacy And Stability - Question 11

Answer: b
Explanation: In these cases, instability is the most probable occurrence, but there are a lot of examples which are unstable.
