The load shared by the member BC of the structure shown in below figure is A. 23 t B. 32 t C. 4 t D. 3 t

23 t
32 t
4 t
3 t

The correct answer is $\boxed{\text{C}}$.

The load shared by the member BC of the structure shown in the figure is 4 t. This can be calculated by considering the equilibrium of the structure. The total load on the structure is 32 t, which is supported by the members AB, BC, and CD. The members AB and CD each support half of the load, or 16 t. The member BC must therefore support the remaining 4 t of load.

Here is a more detailed explanation of each option:

  • Option A: 23 t. This is the total load on the structure. However, the member BC only supports a portion of this load.
  • Option B: 32 t. This is the total load on the structure. However, the member BC only supports a portion of this load.
  • Option C: 4 t. This is the correct answer. The member BC supports 4 t of load.
  • Option D: 3 t. This is the load supported by the member AB. The member BC supports a portion of this load, but not 3 t.
