The rate of mechanical wear is mainly a function of how often a device is activated to make a change.

Also, mechanical wear on bearings increases rapidly with rotational speed, reducing life.

Osteoarthritis is caused by mechanical wear and tear on joints.

Examples for this is mechanical wear, or degradation of the surface of the storage device.

Research is also ongoing to produce more robust systems which are less vulnerable to natural damage, mechanical wear and icing.

Modern engines don't need much time to warm up, so idling creates unnecessary pollution and mechanical wear.

This increased efficiency whilst reducing mechanical wear and the effects of hammerblow on the track.

It was found to have very poor resistance to mechanical wear, mainly abrasion within cable harnesses due to aircraft movement.

Any losses in strength properties are due only to the mechanical wear during the second processing step.

Predictable failures result from slow processes such as mechanical wear and gradual degradation of storage surfaces.
