41. Trommel screens are more mechanically robust than vibrating screens allowing it to last longer under mechanical stress . 42. Temperature changes create thermally induced mechanical stress . 43. The chin emerged during the finite element analyses have been used to support hypotheses involving mechanical stress . 44. Under mechanical stress it is possible for the cover to crack partially or fully, uncovering the conducting element. 45. Mechanical stresses also influence the frequency.46. A considerable amount of design effort went into various devices to relieve mechanical stress due to thermal expansion. 47. The increased torque results in sudden mechanical stress on the machine which leads to a reduced service life. 48. These junctions are most abundant in tissues that are subject to constant mechanical stress such as skin and heart. 49. The flexibility of the peptide backbone determines its ability to stretch which is important for proteins under mechanical stress . 50. This hydration of the surface layers produces a volume expansion which places mechanical stress on the dry subsurface layers.
