Flour suspended in water

In chemistry, a suspension is a dispersion (mixture) in which a finely-divided species is combined with another species, with the former being so finely divided and mixed that it doesn't rapidly settle out. In everyday life, the most common suspensions are those of solids in liquid water.

A suspension of liquid droplets or fine solid particles in a gas is called an aerosol. In the atmosphere these consist of fine dust and soot particles, sea salt, biogenic and volcanogenic sulfates, nitrates, and cloud droplets.

The term is widely used in Earth sciences to describe the transport of sediments in rivers and oceans. Particles that are suspended remain suspended so long as energy (provided in the form of a current) is applied to the system. The amount of energy determines the maximum size of particle that can be suspended. All particles down to colloidal size will settle in the absence of energy (aggitation).

Suspension of disbelief - Wikipedia, the free encyclopedia (664 words)
Suspension of disbelief is a willingness of a reader or viewer to suspend his or her critical faculties to the extent of ignoring minor inconsistencies so as to enjoy a work of fiction.
One of the most well known examples of suspension of disbelief is the acceptance that the iconic superhero, Superman, hides his identity from the world by simply donning a pair of glasses and acting in a "mild mannered" fashion, which contrasts with the large and in-charge personality of Superman.
The example of this is where the character addresses the audience directly (breaking the fourth wall) or otherwise engages with a glance or look or does or says something to show that the character realises that he is a character in a work of fiction.
Double wishbone suspension - Wikipedia, the free encyclopedia (443 words)
The suspension consists of a pair of upper and lower lateral arms, roughly horizontal, and of roughly similar length.
In front view the suspension is a 4 bar link, and it is easy to work out the camber gain (see camber angle) etc, for a given set of bush locations.
The advantage of a double wishbone suspension is that it is fairly easy to work out the effect of moving each joint, so you can tune the kinematics of the suspension easily.
