A balance section is one in which the concrete crushing and steel yielding take place at the same time.
An under-reinforced section in beam design refers to a concrete beam that has insufficient tensile reinforcement to prevent failure by yielding of the steel before crushing of the concrete. This condition is typically characterized by a lower ratio of steel reinforcement to the amount of concrete, resulting in a ductile failure mode. In such a scenario, the steel reinforcement reaches its yield strength before the concrete reaches its ultimate compressive strength, allowing for some warning before failure occurs. This design approach is often preferred as it provides a more predictable and safer collapse mechanism.

the part of beam which has maximum section modulus should take more load for more strength.

Under Reinforced Section
An 'U' beam is a beam that is shaped like the letter 'U'. It is usually made of 3 parts; 2 sides and 1 bottom piece. A beam would normally refer to an 'I' beam (A beam that is shaped like the letter 'I'). The difference is that cross section of the beams are different.
A beam with a uniform cross-section.

what pupose concealed beam use in slab design
First class levers are sometimes referred to as beam balances because they have a beam (or rigid structure) that pivots on a fulcrum, with the load and effort on opposite sides of the fulcrum. This design allows for weight to be balanced and measured, similar to how a traditional balance scale operates.
A seesaw can be balanced with equal weight. I balanced on a ledge, so I wouldn't fall. The gymnast balanced on the beam, after a hand spring.
The neutral surface of a beam is the line along the beam's cross-section that does not experience any stress or deformation when the beam is subjected to bending loads. It is the location where the strain is zero. The neutral surface is typically located at the centroid of the beam's cross-section.

Plastic Section Modulus about the element local y-direction
If you are looking to find alternatives for a cross-section design, it is generally recommended to check both the section modulus and the moment of inertia. The section modulus helps determine the resistance of a beam to bending stress, while the moment of inertia indicates the distribution of an area about a neutral axis. Both parameters are crucial for ensuring the structural integrity and efficiency of the design.

it;s design that way
