Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.
A ball mill is a type of grinder filled with grinding balls, used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
Plastic joint clips Plastic joint clips failing due to corrosive and thermal exposure. Joint clips (or Keck clips) [1] are used to prevent laboratory glassware joints from separating during a reaction process. They are used to secure the two sides together and are available in a variety of materials for different temperature and chemical ...
A typical ball joint with cutaway view (right) An inner tie rod end cut open to expose the ball joint. In an automobile, ball joints are spherical bearings that connect the control arms to the steering knuckles, and are used on virtually every automobile made. [1] They bionically resemble the ball-and-socket joints found in most tetrapod ...
The ring is set with the ball on top with ball guides on the grooved plate within the heating bath. As the temperature rises, the balls begin to sink through the rings carrying a portion of the softened sample with it. The temperature at which the steel balls touch the bottom plate determines the softening point in degrees Celsius. [5] [6]
This can be as simple as deciding what a likely maximum load case is at the contact patch, and then drawing a Free body diagram of each part to work out the forces, or as complex as simulating the behaviour of the suspension over a rough road, and calculating the loads caused. Often loads that have been measured on a similar suspension are used ...

Diagram of a ballbarrow from James Dyson's 1977 patent. The Ballbarrow was a variation of the wheelbarrow design, [1] by James Dyson released in 1974 in the UK. [2] It featured a moulded plastic hopper on a steel frame and a spherical plastic wheel, allowing increased manoeuvrability. Dyson said that the surface area of the ball, larger than ...
