A(n)<u> Solid</u> coupling is used when it is necessary to extend the length of a shaft or to provide a means of disconnecting a shaft.
The basic function of all couplings is to transmit power, accommodate misalignment and compensate for axial movement (end movement of shafts). Sometimes, a coupling is asked to absorb shock or vibration. A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power.
Types of Couplings:
- Rigid coupling.
- Flexible coupling.
- Sleeve or muff coupling.
- Split muff coupling.
- Flange coupling.
- Gear coupling.
- Universal joint (Hooke's joint)

Answer:
Empiricism
Explanation:
Empiricism is an important principle of science. The principle focuses on need of real practical world experiments to validate scientific findings. Solely theoretical reasoning is not sufficient to form a strong base for understanding scientific logics. Testing & encountering, verifying them enable discovering & learning the best form of scientific knowledge. As, it is applicable in real world. For example : A student would better understand the rule of water absorption by a particular item - through really keeping it in water sometime & observing, rather than just listening & learning that.
Therefore, students have labs in science courses in high school, to allow them perform experiments that foster their understanding of the scientific principles

Answer:
Explanation:
es una importante cordillera ubicada en el este de Norteamérica. Se extiende desde la Isla de Terranova en Canadá, pasado por la colectividad de ultramar francés de San Pedro y Miquelón, hasta Alabama en los Estados Unidos, aunque su parte más septentrional termina en la península de Gaspé, en Quebec. Constituye el elemento morfológico más sobresaliente de la parte oriental de América del Norte.
Se originó en antiguas montañas formadas en el periodo Paleozoico con relieves suavizados por la prolongada acción de los agentes exógenos. El sistema está dividido en una serie de cordilleras, en las que la medida de altura de los picos es de unos 1000 m s. n. m. (metros sobre el nivel del mar). La cima más elevada es el monte Mitchell, en Carolina del Norte, mide 2037 m s. n. m. y es el punto más alto de los Estados Unidos al este del río Misisipi y de todo el este de Nor
teamérica.
