Strength Of Material Formula Sheet

Absolutely, here are some key formulas commonly used in Strength of Materials:

Stress and Strain:

  • Stress (σ) = Force (F) / Area (A)
  • Strain (ε) = Change in Length (ΔL) / Original Length (L)

Elasticity:

  • Hooke's Law: σ = E * ε (where E is the Modulus of Elasticity)

Shear:

  • Shear Stress (Ï„) = Force (F) / Area (A)

Beam Bending:

  • Bending Moment (M) = Force (F) x Distance (d)
  • Flexure Formula: σ = My / I (where M is bending moment, y is the distance from the neutral axis, and I is the moment of inertia)

Deflection:

  • Deflection (δ) = (M * L^3) / (EI) (where L is the beam length)

Torsion:

  • Shear Stress (Ï„) = Torque (T) * Radius (R) / Polar Moment of Inertia (J)
  • Angle of Twist (θ) = (TL) / (JG) (where T is torque, L is length, G is shear modulus, and J is polar moment of inertia)

These are just a few basic formulas. Strength of Materials covers a broad range of topics, so depending on your specific needs, you might encounter formulas for:

  • Combined stresses and strains
  • Statically indeterminate beams
  • Columns and buckling
  • Springs
  • Fatigue
