A tractor mounted off-set type reciprocating mower is driven by the PTO shaft. The maximum inertia force of $3.2 \mathrm{kN}$ occurs along the pitman at $32^{\circ}$ crank angle and $27^{\circ}$ pitman angle with the horizontal plane. The knives of the cutterbar are riveted to the slider. If each of the allowable tensile and compressive stresses of the slider material is $50 \mathrm{MPa}$, the minimum cross-sectional area of the slider in $\mathrm{mm}^{2}$ is

(A) 29.05

(B) 33.91

(C) 54.27

(D) 57.02
