Test: Three Hinged Arch - Question 6

What is the degree of indeterminacy of a fixed arch?

Detailed Solution: Question 6

Answer: c
Explanation: It is indeterminate to 3 degrees.

Test: Three Hinged Arch - Question 7

What is the degree of indeterminacy of a two hinged arch?

Detailed Solution: Question 7

Correct answer: A - the degree of static indeterminacy is 1.

The degree of static indeterminacy is the number of extra unknown reactions that cannot be determined using the static equilibrium equations alone.

For a two-hinged arch, each hinge support provides a horizontal and a vertical reaction, so the total number of external reactions is r = 4.

For a planar structure the independent static equilibrium equations are ΣFx = 0, ΣFy = 0 and ΣM = 0, so m = 3.

Therefore the degree of static indeterminacy is r - m = 4 - 3 = 1. Hence option A is correct.

Test: Three Hinged Arch - Question 8

In real life, bending stresses are zero in a three hinge arch.
State whether the above statement is true or false.

Detailed Solution: Question 8

Answer: b
Explanation: In real life, loads are moving which results in generation of bending stresses.
