Answer:
Chemical property
Explanation:
Chemical properties is what makes a compound change entirely to a different substance/compound when it undergoes changes. These changes takes place within. Reactivity, for example is a chemical property. Different metals have different reactivity and thus will react in some unique ways. It is this reactivity that tells how those metal substances can react with other substances to form new substances that are entirely different.
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)
