Q. Stretch forming is a process which involves tensile and bending forces during the operation.
✅ Correct Answer: (A)
true
Explanation: in stretch forming process, stretching of a metal sheet is basically done by holding its edges and bending it on a cylindrical block, simultaneously is known as stretch forming. this process basically involves tensile and bending forces during the operation. in this process, the materials with high ductility are mostly stretched by rigid dies.
