Indian Standard Manufactured Beam having the web-length of 200mm. These are rolled beams. NPB, UB and ISMB are rolled beams, WB are welded beams.
You just take an example as rect section with A=17.6*10=176 mm2 and your I section too has same area of 176 mm2. Calculate moment of inertia of rectangular section I = bd3/12 = 1466.66 mm4 For I section, Width of both flange = 20 mm, thickness of both flange = 4 mm, web length=16 mm, web thickness = 4mm. This gives you the same area A=176 mm2 Now Calculate moment of inertia of I section I =8938 mm4 (Do it from any online converter or by calculations) Now compare both Moment of inertia, I section has approx six times better moment of inertia as compared to rectangular section. Put up this moment of inertia values in deflection and bending stress equations and try to compare both. This is because the material is put up in such a way to get maximum moment of inertia with minimum material and min weight. Finally this is the reason why I beams are preferable over rectangular beams Once Put up this moment of inertia values in deflection and bending stress equations and try to compare both. you will get it in sec

Stress occur everywhere in the beam. Maximum occur at mid span and at support of simply supported beams and cantilever beams respectively - M. Velsamy, Mobile 9884585625
Nominal moment is the entire calculated moment after applying load...
The moment of inertia of a steel section depends on its shape and dimensions. It is a measure of its resistance to bending. It is often calculated using specific formulas for common geometric shapes like rectangles, circles, or I-beams. The moment of inertia is an important parameter in structural engineering for analyzing the bending behavior of steel beams and columns.

the reinforcement which provided at negative moment developed section.
It means a tiny period of time, such as--> I will be there in a moment.
The definition is to make the moment in your writing go longer instead of just going on; you extend it.
The moment arm of resistance refers to the perpendicular distance from the line of action of a resisting force to the axis of rotation. It helps determine the torque generated by the resistance force on a lever or rotating object. A longer moment arm increases the torque generated by the resistance force.
In structural engineering, the relationship between beam deflection and moment of inertia is that a higher moment of inertia results in less beam deflection. Moment of inertia is a measure of an object's resistance to bending, so beams with a higher moment of inertia are stiffer and deflect less under load. This relationship is important in designing structures to ensure they can support the intended loads without excessive deflection.

Flash your high beams once and wait a moment. Most drivers will lower their beams. They maybe having problems though and their low beams may not even work, so take that into consideration before you give them the finger as they roll by.
The importance of shear force and bending moment diagram in mechanics lies in structural design and in deflection of beams.
