Option 2 : 1 and 3 only
→ Dual network's are obtained for both AC & DC circuits satisfying kirchoff's law's i.e. KCL & KVL.
→ Dual networks are obtained in planar networks.
→ Since KVL is dual of KCL; hence mesh equation are dual of nodal equations therefore, statement 3 is correct.

Consider the following statements regarding stress in beam :
1. If a member is subjected to equal and opposite couples acting in the same longitudinal planes, the member is said to be in pure bending.
2. The internal stresses developed in the beam are known as flexural stresses.
3. There is an intermediate surface known as neutral surface, at which the stress is zero.
4. An axis obtained by intersection of the neutral surface and a cross-section is known as neutral axis.
Which of the above statements are correct ?
Option 4 : 1, 2, 3 and 4Explanation: Pure Bending: It is a case where a member is subjected to equal and opposite couples acting in the same longitudinal plane. Flexural stresses: Flexural stress is...

Five boxes B1, B2, B3, B4 and B5 are placed one above the other in racks. The lowermost rack is numbered as one and just above the lowermost is numbered as two and so on. Each box is coloured with different colour such as L1, L2, L3, L4 and L5 (not necessarily in the same order). Two boxes are placed between L2 coloured box and L5 coloured box. Box B1 is not placed immediately above box B3. Box B4 is placed in the top most rack. L1 coloured box is placed immediate above L5 coloured box. Box B3 is coloured with L4. L5 coloured box is placed above L4 coloured box. Box B2 is coloured with L1. Which of the following boxes are placed immediately above and immediately below B5 box respectively?
Option 3 : B2 and B3Five boxes: B1, B2, B3, B4 and B5. Five colour: L1, L2, L3, L4 and L5. 1) Box B4 is placed in the top most rack. 2) Two boxes...
