<span>La respuesta es miercoles. Si ayer (martes) fuese mañana (jueves), hoy sería viernes. Entonces, martes es verdaderamente ayer, pero el borracho piensa que "ayer" es jueves. Piensa que hoy es viernes, pero verdaderamente es miercoles (el día depues de martes). </span>
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)
