Question 2

1 / -0

Consider the following statements :

1. The displacement method is more useful when degree of kinematic indeterminacy is greater than the degree of static indeterminacy.

2. The displacement method is more useful when degree of kinematic indeterminacy is less than degree of static indeterminacy.

3. The force method is more useful when degree of static indeterminacy is greater than the degree of kinematic indeterminacy.

4. The force method is more useful when degree of static indeterminacy is less than the degree of kinematic indeterminacy.

Which of these statements is correct?

1 and 3

2 and 3

1 and 4

2 and 4

Solution

Force method is useful when D_s < D_k

Displacement method is useful when D_k < D_s

Force Method

Displacement Method

1. Unknowns are taken

redundants forces/reactions.

1. Unknowns are taken displacement

2. To find unknown forces

or redundant compatibility

equations are written.

2. To find unknown displacement joint

Equilibrium conditions are written.

3. The number of compatibility

equations needed is equal to

degree of static indeterminacy.

3. The number of equilibrium conditions

needed is equal to degree of

kinematic indeterminacy.
