Semi-trailer aerodynamic devices are devices affixed to semi-trailers, for the purpose of reducing aerodynamic drag caused by air turbulence. The two major types of device in use are trailer skirts (or side skirts ), affixed to the underside of trailers, and trailer tails (or boat tails , or rear fairings ), affixed to the rear.
Telescoping in mechanics describes the movement of one part sliding out from another, lengthening an object (such as a telescope or the lift arm of an aerial work platform) from its rest state. [1] In modern equipment this can be achieved by a hydraulics , but pulleys are generally used for simpler designs such as extendable ladders and amateur ...
It triggers a mechanism that extends the TV across the room on a telescoping shaft, so that Wallace can reach the on/off and channel buttons. When he accidentally tunes into the wrong program, he finds that he has no more balls available; Gromit hands him the TV remote, but he throws it into the hole instead of using it normally.
Telescopic cylinders must only be used in machinery as a device for providing force and travel. Side forces and moment loads must be minimized. Telescopic cylinders should not be used to stabilize a structural component. [4] Hydraulic telescopic cylinders are often limited to a maximum hydraulic pressure of 2000-3000 psi.
The M931 (M932 w/winch) was a semi-tractor used to tow semi-trailers up to 37,500 pounds (17,000 kg). A front-mounted winch was optional. Unlike commercial trucks the fifth-wheel could also pivot side to side, making a more flexible connection to the trailer. Even so, off-road performance was limited. [14]
Bantam D1 plunger suspension. The telescoping covers protect the springs. Maximum travel is probably less than indicated by the amount of inner can (chrome) showing and the position of the chainguard. Note the rod-actuated rear brake. BSA offered D1's with different electrical lighting systems.
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power, torque, and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to ...
Pneumatic telescoping cylinder, 8-stages, single-acting, retracted and extended Telescoping cylinders, also known as telescopic cylinders can be either single or double-acting. The telescoping cylinder incorporates a piston rod nested within a series of hollow stages of increasing diameter.
