Structural Analysis 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 degree of kinematic indeterminacy.The correct answer is (ii) and (iv) (i) and (iv) (ii) and (iii) (i) and (iii) (ii) and (iv) (i) and (iv) (ii) and (iii) (i) and (iii) ANSWER DOWNLOAD EXAMIANS APP
Structural Analysis If there are m unknown member forces, r unknown reaction components and j number of joints, then the degree of static indeterminacy of a pin-jointed plane frame is given by m – r + 2j m + r – 3j m + r + 2j m + r – 2j m – r + 2j m + r – 3j m + r + 2j m + r – 2j ANSWER DOWNLOAD EXAMIANS APP
Structural Analysis A pin-jointed plane frame is unstable if (where m is number of members, r is reaction components and j is number of joints) (m + r)<2j m + r = 2j (m + r)>2j None of these (m + r)<2j m + r = 2j (m + r)>2j None of these ANSWER DOWNLOAD EXAMIANS APP
