Question

Draw a helical spring of circular wire and -in terms of load, dimensions, and material- exress:

-maximum shear stress,

-angular deflection,

-spring rate,

-energy stored,

-volume of spring wire,

-axial deflection, and

-length of spring wire.

Assme reasonable values and estimate factors

Answer 1

Maximum Shear Stress; V1 = $+Fb / L$ $(0 ≤ x ≤ a )$

Angular deflection = $\dfrac{wL⁴}{8EI}$

Energy stored = $\dfrac12kx²$
