Limit Deflection

Limit deflection of about 8 Hz to be reached

w_{\max, 8 Hz} \approx - k_{f}^{2} \cdot \frac{63 \cdot l^{2} \cdot (12 \cdot l_{k}^{3} - 10 \cdot l_{k} \cdot l^{2} - 3 \cdot l^{3})}{f_{e, 8 Hz}^{2} \cdot l_{k}^{4} \cdot (2 \cdot l_{k} + 3 \cdot l)} = - 1.00 mm

w_max,8Hz	Limit deflection of about 8 Hz to be reached
k_f	Correction factor (see PDF file)
l	Length of the middle span
l_k	Length of the outer panels
f_e,8Hz	Minimum natural frequency
