For example, repeated impacts may cause stress to a hammer's head. This stress is impossible to prevent in the normal use of the tool for its designed task, and any attempt to avert it impedes its functionality. At the same time, it is expected that the normal use of a hammer will not break it beyond repair during a reasonable life cycle.
Heat stress causes illness but also may account for an increase in workplace accidents, and a decrease in worker productivity. [5] Worker injuries attributable to heat include those caused by: sweaty palms, fogged-up safety glasses, and dizziness. [2] Burns may also occur as a result of accidental contact with hot surfaces or steam.
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 ...
Air bag or air strut failure is usually caused by wet rust, due to old age, or moisture within the air system that damages it from the inside. Air ride suspension parts may fail because rubber dries out. Punctures to the air bag may be caused from debris on the road. With custom applications, improper installation may cause the air bags to rub ...
A strut is a structural component that combines the shock absorber with other suspension parts like the coil spring and steering knuckle into one compact unit [15] Unlike a shock absorber, a strut has a reinforced body and stem.
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. [1] Suspension systems must support both road holding/handling and ride quality, [2] which are at odds with each other. The tuning of suspensions involves finding the right compromise.

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.
