materials and using Solid Edge to determine the Second Moment of Area for the different cross-sections. [pic] Equations Use units: Force (N)‚ Length (mm)‚ Stress (MPa) E = Young’s Modulus or Mod of Elasticity (MPa) I = 2nd Moment of Area or Area Moment (mm4). Can calculate using SolidEdge sketch. BENDING [pic] In our case‚ we must first convert the mass to Newtons (N). W = kg * 9.81 L is the span length in (mm). I is the Second Moment of Area in (mm4). We can calculate this for a rectangle
