Attached is a cross section design for a prototype wingbox made in Aluminium Sheet. $($in mm$)$

Aluminum Sheet Data:

$196$ MPa Tensile Strength

$166$ MPa Yield Strength

$15070$ MPa Young's Modulus

Bending Test Result of the wingbox:

Maximum Force: $50\mathrm{.}44$ kgf

Maximum Displacement: $22\mathrm{.}13$ mm

Cross Section Size:

$68$mm Wide

$250$mm long

$82$mm Tall

Please help me with below task:

Plot the shear force and bending moment diagrams

Identify maximum shear force and maximum bending moment and their corresponding locations

Calculate the maximum load that can be applied to the wing box
