Problem

A steel leaf spring, treated as a cantilever, has rectangular cross-section

b = 40\,\mathrm{mm}

wide and

h = 6.0\,\mathrm{mm}

thick, free length

L = 0.50\,\mathrm{m}

, and

E = 200\,\mathrm{GPa}

. A transverse tip load

F = 20\,\mathrm{N}

is applied at the free end. ((a)) Find the tip deflection. ((b)) Find the maximum bending stress, which occurs at the clamped root.
