The correct answer is: B. More than the load factor in determinate structures.
A determinate structure is a structure in which the internal forces can be determined by static equilibrium alone. An indeterminate structure is a structure in which the internal forces cannot be determined by static equilibrium alone and additional information, such as the deformation of the structure, is required.
The load factor is a factor that is used to increase the design loads on a structure to account for uncertainties in the loads and the strength of the materials. The load factor is typically greater for indeterminate structures than for determinate structures because indeterminate structures are more susceptible to failure due to unforeseen loads or material defects.
Here is a brief explanation of each option:
- Option A: Equal to load factor in determinate structures. This is not correct because the load factor is typically greater for indeterminate structures than for determinate structures.
- Option B: More than the load factor in determinate structures. This is the correct answer because indeterminate structures are more susceptible to failure due to unforeseen loads or material defects.
- Option C: Less than the load factor in determinate structures. This is not correct because the load factor is typically greater for indeterminate structures than for determinate structures.
- Option D: Unpredictable. This is not correct because the load factor can be determined based on the type of structure and the loads that it will be subjected to.
