different available materials. From this point of view paper deal with a set of major gear design criteria which are used for gear material selection. The main gear design criteria are: surface fatigue limit index‚ bending fatigue limit index‚ surface fatigue lifetime index‚ bending fatigue lifetime index‚ wear resistance of toots flank index and machinability index. Using computer allows a large amount of information to be treated rapidly. One the most suitable model‚ for ranking alternatives

the structural ‘Aspect Ratio’ and the ‘Thickness Ratio’ of aerofoil sections. An aspect ratio is the span of an aircrafts wings‚ from tip to tip all along the axis of symmetry of the aeroplane. The more the aspect ratio of a wing the greater the bending forces by the lift at the root. The thickness of a high aspect

were seriously injured. This accident occurred because the braking system was not properly designed. Operation of the brake over its lifetime produced higher than estimated bending forces on the system and induced fluctuating stresses on the braking rod that it could not sustain. Crack propagation developed in the rod due to bending stresses and eventually extended until fracture occurred‚ sending the cage of men to the bottom of the shaft at nearly 30 miles per hour.

Types of joints: Ball-and-socket joint: Consists of a bone with a globular or slightly egg-shaped head that articulates with the cup-shaped cavity of another bone. Such a joint allows a wider range of motion than does any other kind‚ permitting movements in all planes‚ as well as rotational movement around a central axis. The hip and shoulder contain joints of this type. Condyloid joint: The ovoid condyle of one bone fits into the elliptical cavity of another bone‚ as in the joints between the

It was found that the concrete columns exhibited complicated behaviour‚ and had a squash load point of 342.7KN and moment at 0 KN.m‚ a decompression point of 227.75 KN and moment at 2.92 KN.m‚ a balanced point (nominal) of 58.46 KN and moment at 3.81KN.m‚ a pure bending point of 0 KN and moment at 2.86 KN.m‚ a balanced

and become the opposite sex. There are different words for the gender changes: transsexuals are those who undergo sex-change surgery; transvestites are those who dress in the opposite genders clothes. According to Lorber this would be called gender bending and she explains how she perceives how people perform gender. Risman explains her three levels of differentiation and she incorporates it with how she thinks people perform gender. Gender is something so routine and everyone does it everyday. Judith
