Lee at el. [1] has studied the dynamic behavior under lateral force with constant velocity and magnitude moving axially a simply supported shaft based on Euler-Bernoulli, Rayleigh and Timoshenko beam theories.
Shiau at el [10] have been studied the dynamic response of a single span shaft with general conditions.

Takenaka et al [4] reported that the hydrolysate of lemon pectin might exhibit antibacterial activity and linked this activity to the galacturonan oligomers.
Matsuda et al. [15] reported that the MICs of lactic acid against lactic acid bacteria (L. casei, L. lactis) at pH 5 and pH 6 were much higher than that of B. subtilis and S. aureus.

Rahmanifard et al. (2010) have found that higher BPR required longer time to achieve an equilibrium state compared to lower BPR.
The crystallite size of Fe for BPR 5:1 until 10:1 decreased with the increased of BPR which is in accordance with Boytsov et al. (2007) who have reported that the crystallite size is logarithmatic function with the BPR.

Al-10Sr is most effective to refine microstructure and improve mechanical properties of AS31 alloy.
The 0.2% yield strength (YS), ultimate tensile strength (UTS) and elongation to rupture (El.) were averaged over three specimens.
And 1 wt.% Al-10Sr is most effective to modify the Mg2Si phase.
And 1wt.% Al-10Sr improves the ultimate strength, yield strength and elongation to 126.1MPa, 96.1MPa and 7.5%.
And 1 wt.% Al-10Sr is most effective to refine grains and modify the Mg2Si phase.

This is in agreement with the theoretical results of Hugosson et al. [12] which showed no significant change in the lattice parameter for TiCx coatings with stoichiometries in the range TiC0.5–TiC1.0 [12].
Similar XRD peak shifts have been noted by Inoue et al. [14] and Fujihana [15] for such strongly substoichiometric TiCx compositions.

Wu et. al., studied Ti-Mn-Zr ternary system concerning the isothermal sections of the Ti-Mn-Zr ternary system at 1020 and 800 °C[8].
Also, Kazuyuki et al [9] presented Ti-10Zr titanium alloy claiming its good cold workability, high strength and ductility.This motivated us to study the different properties the mechanical properties for the Ti-14Mn-Zr ternary system.
