In case of a suspension bridge, the cable is used to suspend the bridge deck so that the load is transferred through the cable. During the analysis of such a cable, which of the following statement(s) is / are not correct? i. The bending moment is transferred from suspenders to the cables rigidly ii. The cable is inextensible so that the minor changes in length can be ignored iii. The cables are considered to carry uniformly distributed load iv. The shape of the cables which they take in resisting the loads are funicular
- AOnly (i)Correct
- B(i) and (ii)
- C(ii) and (iii)
- D(iii) and (iv)
Solution
Concept
Cable assumptions
Step-by-step solution
1. A cable is perfectly flexible and carries no bending moment. 2. Statement (i) is therefore wrong.
Explanation
Other statements are standard cable assumptions.
Correct answer: A) Only (i)
