JAMB - Physics (2019 - No. 23)
The diagram above represents the stress-strain graph of a loaded wire. Which of these statements is correct?
At J, the wire becomes plastic
J is the yield point
L is the elastic limit
At K, the wire breaks
Explication
- I is the elastic limit
- the end of the constant part J is the yield point
- L is the break point.
- the end of the constant part J is the yield point
- L is the break point.
