Worked Solution & Example Answer:Explain the term temporary joint - Leaving Cert Engineering - Question e, f, g - 2018
Step 1
Explain the term temporary joint.
Answer
A temporary joint refers to a connection that is designed to be easily disassembled or removed. Such joints are commonly used in situations where components need to be joined for a specific task but may need to be separated later. Examples include soldered connections that can be unsoldered, or mechanical fasteners like clamps and screws, which allow for disassembly.
Step 2
Explain why the LED shown has one short leg.
Answer
The short leg on an LED (Light Emitting Diode) is connected to the negative side of the battery, which indicates the cathode. The longer leg corresponds to the positive side (anode). This design feature helps users easily identify how to correctly install the LED in a circuit.
