How It's Made is a documentary television series that premiered on January 6, 2001, on the Discovery Channel in Canada and Science in the United States. The program is produced in the Canadian province of Quebec by Productions MAJ, Inc. and Productions MAJ 2.
Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. [7] [8] Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. [9] [10] [11] Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body.
The video for "She Blinded Me with Science" was conceived and storyboarded before the song was written. [9] Dolby added the song title, wrote the song to fit the planned video, and then directed the music video. [10] The video features Magnus Pyke as The Doctor, at "The Home for Deranged Scientists".
The moving part then decelerates to a stop from the dynamic contact friction. The cycle repeats as the forcing element catches up to contact again. Stick, store spring energy, impulsively release spring energy, accelerate, decelerate, stop, stick. Repeat. Stiction is a problem for the design and materials science of many moving linkages.
Abrasion is the natural scratching of bedrock by a continuous movement of snow or glacier downhill. This is caused by a force, friction, vibration, or internal deformation of the ice, and by sliding over the rocks and sediments at the base (that also causes an avalanche) that causes the glacier to move.
The evolution of the disk's axial precession is easily visualized in a slow motion video by looking at the side of the disk following a single point marked on the disk. The evolution of the rotation of the disk is easily visualized in slow motion by looking at the top of the disk following an arrow drawn on the disk representing its radius.
Charles Haldat made some penetrating criticisms of the reproducibility of Rumford's results [15] and it is possible to see the whole experiment as somewhat tendentious. [16] However, the experiment inspired the work of James Prescott Joule in the 1840s. Joule's more exact measurements were pivotal in establishing the kinetic theory at the ...
The owner winds the spring up by turning the crank. Then when the light is turned on (by releasing a mechanical brake), the spring unwinds, turning a generator to provide power to run the light. The purpose of this design, originally invented for use in the developing world, was to improve its reliability and useful lifetime by avoiding or ...
