-> when a structural body gets deviated from its original position or from its centroidal axis due to externally applied load,then it is termed as BENDING
->DIRECT STRESS is the stress which act normal to the plane
-> stress and bending are the two different things. stress produced by load per area & bending is the effect produced by load and stress.

What are the permissible tensile and bending stress values for M20 concrete?
20kn/mm2
Why shear stresses are maximum at neutral axis?
according to bending stress because shear stress at neutral is 0 that is why shear force is maximum
What is the difference between a load-controlled tensile test and a displacement-controlled tensile test?
If the test is set to load-control , it means that the stress will not drop once the fracture become unstable. In displacement control the stress may drop at unstable fracture.
How curtailment is done rcc beams?
in case of beam bottom most fiber taking bending stress and stress gradually decrease toward supporting members longitudinally. so that curtailment can be done by analysis cross section of the beam and can be determined steel required particular section.
What are the bending moment?
Positive and Negative are just directions. The main concern is whether there exist a bending moment or not. Then according to sign convention we classify bending moment as positive or negative. Elaborating on this point, If clockwise bending moments are taken as negative, then a negative bending moment within an element will cause "sagging", and a positive moment will cause "hogging" Sagging and hogging moments are important to differentiate. As hogging causes tension in the upper part of the beam x-section whereas sagging causes tension in the lower part of the x-section. This concept is of great importance in designing reinforced concrete members as we have to provide steel rebar in the zone of beam having tensile stress as concrete is weak in tension.
What is the difference between Bending STRESS and Direct Stress?
direct stress is a stress normal to the cross section, A, and is the result of an axial load, P. direct stress = P/A Bending stress also acts normal to the cross section but varies from tension on one side and compression on the other. and is the result of a bending moment, M. bending stress = Mc/I where I is the area moment of inertia and c the distance from outer fiber to neutral axis
Difference between unsymmetrical and symmetrical bending?
Symmetrical bending occurs when a beam is loaded uniformly along its length, resulting in bending stresses that are equal on both sides of the beam's neutral axis. Unsymmetrical bending occurs when a beam is loaded unevenly, causing different magnitudes of bending stress on opposite sides of the beam's neutral axis.
What is the relationship between bending and strain?
From the Hooke law, stress s is proportional to strain e; s = Ee where E is elastic modulus of the material; the stress is the bending stress which varies from plus on one surface to minus on the opposite surface.
What is difference between stress and intonation?
the differences between intonation and stress is the difference . ! :D :D hahahahahaa
Is bending stress is directly proportional to section modulus?
Yes, bending stress is directly proportional to the section modulus. A larger section modulus indicates that the cross-sectional shape of the member is better at resisting bending, leading to lower bending stress. Conversely, a smaller section modulus results in higher bending stress for the same applied bending moment.
What is allowable bending stress for en-8 shaft material?
allowable bending stress for en8
What is the allowable bending stress for EN-8 shaft material?
allowable bending stress for en8
What is the difference between deflection and bending?
Bending moment With "bending" you really mean the bending moment. The bending moment in an inner stress within a member (usually beam) that allows it to carry a load. The bending moment doesn't say anything about how much a beam would actually bend (deflect). Deflection Deflection measures the actual change in a material you could call "bending." It measures the physical displacement of a member under a load.
Is bending stress and shear stress are same are not?
no
Relation between tensile stressbending moment and section of modulus?
The relation between bending moment and the second moment of area of the cross-section and the stress at a distance y from the neutral axis is stress=bending moment * y / moment of inertia of the beam cross-section
What is the difference between C16 and C24 stress grading?
C8 stress
What is caused by stress and the bending tiliting and breaking of rock?
Stress changes the shape or breaks (fractures) rocks whereas bending leads to folding
