if the bar length is 5o m , what will be the actual length including lap length
When a simply supported beam is subject to bending; the top of the beam will be subject to compression, and the bottom of the beam will be subject to tension (think about the bottom of the beam stretching as it bends i.e. tension). Concrete is strong in compression but weak in tension, so steel reinforcement is added to allow it to resist this tension and carry bending sufficiently. Note: bars are generally added to the compression side too but that's for another day.
How reinforcement steel reconcile.
The reinforcement resisting flexure (bending) in the direction of the span.
Curtailment is a theoretical point where some of the reinforcement is cut-off along the span of the beam where the bending moment reduces, given that the remaining reinforcement will be able to support the reduced bending moment. (A.P Nangolo)

Steel is stronger than concrete. By adding some reinforcement in the compression zone of a beam, it's bending strength can be increased without increasing the size of the beam. The steel increases the compression strength, while the concrete prevents the slender steel bars from buckling.
bar cranking is the process of bending up the bottom steel bars in upward direction. it is mainly to prevent upward bending moment near the joint. also useful for attaching stirrup bar efectivly. cranking is also used in two way slabs
A common characteristic of reinforced concrete bridges is that they feature a combination of concrete and steel reinforcement to provide added strength and durability. The steel reinforcement helps to enhance the tensile strength of the concrete, allowing the bridge to better withstand forces like tension and bending.

The reinforcement effect is the result reinforcement on behavior. It is used to study the success rate of positive, negative, and partial reinforcement.
Partial reinfocement is more attrective than continuous reinforcement and partial reinforcement satisfied more than continuous reinforcement
