How does strain comes in a bar when it is fixed from both the ends? If strain is produced, does that mean the length of bar is increased when it is fixed?

It's neutral... No increase or decrease

If we talk about a bar with both end fixed, then strain never come. But there may be a stress for example if you give heat to a bar with both end fixed then compressible stress are there.

Because of bending moment stain introduced , length of bar increased , it bents by its own weight or applied load

Strain does not only depend on fixture. It depends on the type of load (i.e. tension, compression, torsion etc.) you are applying and accordingly you will see the strain. In universal testing machine (UTM), specimen is always fixed on both ends but the loading is tensile therefore, one observes axial...

When the bar is fixed from both ends then strain of the bar should be zero.because in this case change in length is zero.and strain is change in length/original length

In a bar fixed at both ends if we increase or decrease the temperature thermal stress will be induced as the elongation and contraction is restricted at both ends but there will be no thermal strain. Also there can be no tensile or compressive strain in the bar. But due to bending there can be strain...

Also there can be no tensile or compressive strain in the bar. But due to bending there can be strain induced in the bar because in that case the length of the longitudinal fibres will change above and below the neutral fibre. read less

In my opinion, it can come, but then the assumption made in strength of material of homogeneous, isotropic and prismatic pair will be violated, and it may be because of change of shape due to bending moment.

As the bar has its own weight, when it is fixed on two sports the weight of the bar itself acts as a load to it. Eventually the bar experiences a little contraction in the lateral end and little expansion in the other surface.

Is coaching important for the class 12 science exam?
No need. The thing is you must have basics and be upto date in reading and learning. Just need a compressuve reading of lessons as many times as possible and practice bits questions. It is enough to get good result.
