Fatigue life of a material for a fully reversed loading condition is estimated from <sub>a</sub> = 1100 N<sup> 0.15</sup> where <sub>a</sub> is the stress amplitude in MPa and N is the failure life in cycles. The maximum allowable stress amplitude (in MPa) for a life of 1 10<sup>5</sup> cycles under the same loading condition is_______(correction to two decimal places).
For ball bearings, the fatigue life L measured in number of revolutions and the radial load P are related by FL<sup>1/3</sup> = K, where K is a constant. It withstands a radial load of 2 kN for a life of 540 million revolutions. The load (in kN) for a life of one million revolutions is ______.

Ball bearings are rated by a manufacturer for a life of 106 revolutions. The catalogue rating of a particular bearing is 16 kN. If the design load is 2 kN, the life of the bearing will be P x 10<sup>6</sup> revolutions, where P is equal to _________
A self-aligning ball bearing has a basic dynamic load rating (C<sub>10</sub>, for 10<sup>6</sup> revolutions) of 35 kN. If the equivalent radial load on the bearing is 45 kN, the expected life (in 10<sup>6</sup> revolutions) is
At a critical point in a component, the state of stress is given as <sub>xx</sub> = 100 MPa, <sub>yy</sub> = 220 MPa, <sub>xy</sub> = <sub>yx</sub> = 80 M Pa and al l ot her st r ess components are zero. The yield strength of the material is 468 MPa. The factor of safety on the basis of maximum shear stress theory is_____ (round off to one decimal place).
A machine element is subjected to the following bi-axial state of stress; <sub>x</sub> = 80 MPa; <sub>y</sub> = 20 MPa; <sub>x</sub> = 40 MPa. If the shear strength of the material is 100 MPa, the factor of safety as per Tresca's maximum shear stress theory is
