Question

Neglecting self weight, which of the following beams will have points of contraflexure?

• A. A simply supported beam with uniformly distributed load over part of the structure
• B. An overhanging beam with loading only over supported span and not on overhangs
• C. Fixed beam subjected to concentrated load
• D. Cantilever beam subjected to uniformly varying load with zero load at free end

Answer 1

The correct option is C Fixed beam subjected to concentrated load

(c)

Beam and loading	Points of contraflexure
(i) Simply supported beam with UDL over part of the structure. (ii) An overhanging beam with loading only over supported span not on overhangs. (iii) Fixed beam subjected to concentrated load. (iv) Cantilever beam subjected to UDL with zero load intensity at free end.	zero zero Two zero
