CE Quiz 13

Which of the following is the purest form of iron

what is the carbon content in composite of pig iron

The modules of elasticity for aluminium

What is the percentage elongation at failure of mild steel in tension

The point on the stress-strain curve up to which if the load is removed, the original volume and shape of the body are regained is called as:

The slope of the stress-strain curve within the elastic deformation region is:

If Young’s modulus of a material is 1.5 MPa and its Poisson’s ratio is 0.4, then the Modulus of rigidity is

The Bulk modulus (K) of a material is 100 GPa. Determine the Poisson’s ratio if the modulus of elasticity (E) is 120 Gpa.

Compatibility conditions specifies:

A fixed bar of length 1.5 m is subjected to a temperature rise of 40˚C . The stresses induced in the bar if modulus of elasticity of material is 25000 kg/m³ and coefficient of thermal expansion is 2 × 10^-4/˚C
