137) Study the following statements. i) The displacement method is more useful when degree of kinematic indeterminacy is greater than the degree of static indeterminacy. ii) The displacement method is more useful when degree of kinematic indeterminacy is less than the degree of static indeterminacy. iii) The force method is more useful when degree of static indeterminacy is greater than the degree of kinematic indeterminacy. iv) The force method is more useful when degree of static indeterminacy is less than the

Answer is:

(ii) and (iv)

138) Select the correct statement

Answer is:

both Flexibility matrix is a square symmetrical matrix and Stiffness matrix is a square symmetrical matrix

139) To generate the j th column of the flexibility matrix

a unit force is applied at coordinate j and the displacements are calculated at all coordinates

a unit displacement is applied at co-ordinate j and the forces are calculated at all coordinates

a unit force is applied at coordinate j and the forces are calculated at all coordinates

a unit displacement is applied at co-ordinate j and the displacements are calculated at all co-ordinates

Answer is:

a unit force is applied at coordinate j and the displacements are calculated at all coordinates
