May increase or decrease
Does not change
Decreases
The limit beyond which the material does not behave elastically is known as
Proportional limit
Plastic limit
Elastic limit
Yield Point
The section modulus of a rectangular section(b*d) about an axis through its C.G. and parallel to the base ‘b’ is
bd3/3
