Background Information
  • Ladder Evaluation
    • Weight
    • Density of Steel:
background information cont
Background Information Cont.
  • Shear Stress – stress applied parallel to the face of a material
      • - the applied force
      • - area to which the force is applied
  • Moment of Inertia – rotational analog of mass
      • - the diameter
background information cont8
Background Information Cont.
  • Maximum Deflection
      • - the elasticity of the material
      • - the length
  • Bending Stress
      • - the moment of fixed ends
      • - the perpendicular

distance to the

neutral axis
