Final answer:
Keyways and pin joints offer increased torque transmission and easy assembly and disassembly.
Step-by-step explanation:
Keyways and pin joints have several advantages in engineering:
- Increased torque transmission: Keyways and pin joints provide a secure connection between two components, ensuring that torque is transmitted effectively from one component to another. This is especially important in applications where high torque or rotational forces are involved, such as in machinery or mechanical systems.
- Easy assembly and disassembly: Keyways and pin joints allow for convenient and quick assembly and disassembly of components. This is beneficial when maintenance or repairs are required, as it reduces downtime and makes the process more efficient.
