Topic: Strength of Materials
A body which is permanently deformed is said to have undergone
- A. Elastic deformation
- B. Limit of elastic deformation
- C. Plastic deformation
- D. Uniform deformation
Answer: C. Plastic deformation
Explanation: Plastic deformation is the process in which the object changes its size or shape that is not reversible because of the applied force. So, a body which is permanently deformed is said to have undergone plastic deformation.
