A gas spring consists of a sealed cylinder filled with a charge of high-pressure [5] gas, a piston rod attached to a piston with a sliding seal, and some oil. [1] The piston (or the cylinder wall) contains a number of channels that allow the gas to transfer between the lower chamber (between the piston and the closed end of the cylinder) and the upper chamber (between the piston and the head ...
Employers must provide PPE when other control measures are still being developed or cannot adequately reduce hazardous exposure to safe levels. [16] Personal Protective Equipment (PPE) minimizes risks to health and safety when worn correctly, including items like earplugs, goggles, respirators, and gloves.

Strut is a common name in timber framing for a support or brace of scantlings lighter than a post. Frequently struts are found in roof framing from either a tie beam or a king post to a principal rafter. Struts may be vertically plumb or leaning (then called canted, raking, or angled) and may be straight or curved.
Unlike a shock absorber, a strut has a reinforced body and stem. Struts are subjected to multidirectional loads, while a shock absorber only damps vibration, only receiving a load along its axis. Struts and shock absorbers have a different way of attachment. Shock absorbers are mounted through rubber or urethane bushings to the frame and ...
Tread worn away completely: especially when the wear on the outer rubber exposes the reinforcing threads within, the tire is said to be bald and must be replaced as soon as possible. Sometimes tires with worn tread are recapped, i.e. a new layer of rubber with grooves is bonded onto the outer perimeter of a worn tire. Since this bonding may ...
