6.2. For bending about the axis that has the largest moment of inertia and section modulus, the axis is called the strong (major) axis in contrast to the other one, which is called the weak (minor) axis. Traditionally, the strong axis is assigned as x-axis. For I-sections, box ...
This is associated to a main mechanical relaxation occurring at about 45–48 °C, as assessed by dynamic mechanical analysis (DMA) at the peak of the loss modulus E″. Above 75–80 °C, the measurement of the moduli is no longer possible in DMA because of material flow. The filaments ...

Stress: As we know that when the force is applied over the surface area then there is a development of internal restive force inside the body and this type of force is called stress. The stress may be many types like shear stress, longitudina...
From the angle of saving material, the author make the related computing, as well as compare and analysis to the biggest torsion shearing stress of the hollow or solid circle cross section shaft. Simultaneously it is elaborated, when the most torsion shearing stress of the hollow circular cross...
Assuming that the absorbing atoms or ions are undergoing a TPA transition between nondegenerated energy levels Ee and Eg, the cross-section σ is proportional to the square modulus of the TPA transition matrix element Mg→e. The expression of Mg→e is obtained from a second-order time-depende...
