If the weight of the bird makes the wire bend with each side of the wire making an angel Ф with the vertical.
Then 2 T CosФ = W = balancing forces in vertical direction.
T = W / (2 CosФ) = W/2 if Ф ≈ 0degree or very small.

Explanation:
To find the work done against friction during the motion of the crate, we need to consider the change in kinetic energy of the crate from point A to point B.
The work done against friction can be calculated using the work-energy theorem, which states that the work done on an object is equal to the change in its kinetic energy.
Step 1: Calculate the initial kinetic energy:
The initial velocity of the crate at point A is given as 1.2 m/s. The mass of the crate is not given, so we cannot directly calculate the kinetic energy. However, we can assume that the crate is moving with negligible friction at point A, so the work done against friction is zero. Therefore, the initial kinetic energy of the crate is also zero.
Step 2: Calculate the final kinetic energy:
The final velocity of the crate at point B is given as 8 m/s. Again, the mass of the crate is not given, but we can assume that the crate is moving with negligible friction at point B. In this case, the work done against friction is again zero. Therefore, the final kinetic energy of the crate is also zero.
Step 3: Calculate the change in kinetic energy:
Since the initial and final kinetic energies are both zero, the change in kinetic energy is also zero.
Step 4: Calculate the work done against friction:
The work done against friction is equal to the change in kinetic energy, which is zero.
Therefore, the correct answer is option 1: 860 Nm.
