The maximum bending moment of the center of laminated spring of span L due to load W is given by-
WL/4
The bending moment M(x) at this section is the sum of the moments of all forces to one side of the section. Location Bending Moment Formula Value at Center (x=L/2) At a distance x from support (for 0 \le x \le L/2) M(x) = (W)/(2) × x N/A At the center (x=L/2) M_{max} = M\left((L)/(2)\right) (WL)/(4) Therefore, the maximum bending moment at the center of the laminated spring under a central load W is (WL)/(4). Therefore, the correct answer is WL/4.
