In 2011, there were 6,767 new cases of oral cancer in the UK: 4,510 (67%) in men and 2,257 (33%) in women, giving a male:female ratio of around 20:10.[ 1-4 ] The crude incidence rate shows that there are 15 new oral cancer cases for every 100,000 males in the UK, and 7 for every 100,000 females.
A strut is a structural component designed to resist longitudinal compression. Struts provide outwards-facing support in their lengthwise direction, which can be used to keep two other components separate, performing the opposite function of a tie.
Struts perform two main jobs. First, struts perform a shock damping function like shock absorbers. Internally, a strut is similar to a shock absorber. A piston is attached to the end of the piston rod and works against hydraulic fluid to control spring and suspension movement. Just like shock absorbers, the valving generates resistance to pumping forces created by the up and down motions of the suspension.
