Module 3: (13 hours)
Springs: bending and torsion springs, beam of uniform strength, spring constants for Leaf spring and closely coiled helical spring under axial loads. Design of pressure vessels, stresses in thin cylinders’ volume change, Lame’s equation for thick cylinders. Elastic stability of columns, axially loaded short column, Euler’s theory for slender column and Rankine’s formula for intermediate columns. Elementary concept of theories of failure
