On automobiles, disc brakes are often located within the wheel A drilled motorcycle brake disc. The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated similarly to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. [4]
In computational geometry, the method of rotating calipers is an algorithm design technique that can be used to solve optimization problems including finding the width or diameter of a set of points. The method is so named because the idea is analogous to rotating a spring-loaded vernier caliper around the outside of a convex polygon . [ 1 ]
[4] [5] Although rare finds, calipers remained in use by the Greeks and Romans. [5] [6] A bronze caliper, dating from 9 AD, was used for minute measurements during the Chinese Xin dynasty. The caliper had an inscription stating that it was "made on the gui-you day, [a] the first day [b] of the first month of the first year of Shijianguo.
In this situation, a limited-slip differential prevents excessive power from being allocated to one wheel, and so keeps both wheels in powered rotation. [6] The advantages of LSD in high-power, rear-wheel drive automobiles were demonstrated during the United States "Muscle-Car" era from the mid 1960s through the early 1970s.
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.
It pushes the elevator control forward as the stall is approached, causing a reduction in the angle of attack. In generic terms, a stick pusher is known as a stall identification device or stall identification system. [73] A stick shaker is a mechanical device that shakes the pilot's controls to warn of the onset of stall.
Triboelectric powder separation has been discussed as a method of separating powders, for instance different biopolymers. [134] The principle here is that different degrees of charging can be exploited for electrostatic separation, a general concept for powders. [135]
