Q5. What is flexural strength? And what does it shows?
ANSWER:
Flexural strength is a measure of the tensile strength of concrete beams or slabs. Flexural strength identifies the amount of stress and force an unreinforced concrete slab, beam or other structure can withstand such that it resists any bending failures. Flexural strength is also known as bend strength or modulus of rupture or fracture strength.
Q6 Answer:
Flexural testing is used to determine the flex or bending properties of a material. Sometimes referred to as a transverse beam test, it involves placing a sample between two points or supports and initiating a load using a third point or with two points which are respectively call 3-Point Bend and 4-Point Bend testing.
Q7.Answer: Flexural strength depends on Moment of inertia of beam, Section modulus , Materail of beam, stress of beam etc
