Is ultimate flexural strength and moment of resistance the same in a reinforced section?

No the moment of resistance is a defining parameter that can be used to calculate the stress in a cross section of a given material that is subject to flexural loading. The ultimate flexural strength is a numerical value of stress at which the material will crack, tear, rip etc. Think about ultimate tensile strength and the value of Young's Modulus. Young's Modulus is not defined at the point of 'necking' and therefore the ultimate tensile strength cannot be computed from Young's Modulus and Hook's Law, but the UTS is an empirically defined value.

Can the Yield strength of steel ever be greater than the Ultimate tensile strength?
The yield strength is reached when the material becomes non - linear ( that is non elastic) and takes a permanent set when load is released. Material stretches but does not break. Ultimate strength is when it breaks and is higher than yield strength.
Why rupture strength is preferred to ultimate rupture strength?
Ultimate strength is used for materials that yield before breaking, like metals; rupture strength is for materials that break suddenly, like glass. Ultimate rupture strength would imply some yield strength before finally breaking and is not a preferred term for brittle materials like glass.
What is the yield strength of plain concrete?
The yield strength in this case is equal to the ultimate tensile strength, which is about 0.9-3 MPa without any reinforcement.
What is the 21 days strength of concrete?
I think its 90% of ultimate strenght
When does Necking of a metal occur under tensile stress?
after ultimate tensile strength (UTS)
What is ultimate bending strength?
It is the maximum stress at which a material will fail when subject to flexural ( moment producing) bending loads. These stresses occur a the material outer fibers.
What is polycarbonate impact resistance?
Mechanical properties of a polycarbonate sample: Specific gravity (ASTM D 792) : 1.20 Tensile strength, Ultimate (ASTM D 638) : 9,000 p.s.i. Elongation at break (ASTM D 638) : 130% Tensile modulus (ASTM D 638) : 3.1x10~5 p.s.i. Rockwell hardness (ASTM D 785) : R118 Impact strength (73° F) (ASTM D 256) (notched) : 17.0 ft-lb/inch Flexural strength (ASTM D 790) : 14,200 p.s.i. Flexural modulus (ASTM D 790) : 3.4x 10~5 p.s.i. Wear factor against steel 40 psi 50fpm : 2500x10~10 Coefficient of friction 40psi 50fpm : 0.38 Dynamic
How do you convert brinell hardness number to ultimate tensile strength?
Ultimate Tensile Strength is the (BHN*500)
Ultimate strength of SS304?
The ultimate strength of annealed SS304 is 80,000 psi (550 MPa). Its yield strength is 30,000 psi, and its shears strength is 80000/(SQRT(3)) = 46000 psi. If it is cold worked, as for bolts, its yield and ultimate and shear strength will increase.

What is the property of strength?
ultimate strength is the value at which something breaks, and yield strength is the value at which something exhibits a permanent deformation after load.
