Lesson 5
Modulus of elasticity
Young's Modulus [N/m^2] = PL / Ax
P = load
L = original length
A = area
deformation
Stress classification
Normal stress
Tension
Compression
Normal stress [N/m^2] = Force(N) / Area (m^2)
Bending
Shear stress
Shear stress [N/m^2] = Force(N) / Area (m^2)
Torsion
Young's Modulus
Young's Modulus [N/m^2] = stress [N/m^2] / strain [no unit]
Strain
Strain = change in length [m] / original length [m]
Safety factor
SF = Ultimate stress [material strength] / Allowable stress [design strength]
Force is an action that can create motion in the object or resistance motion of the object.
Stress is a measure of how much force an object experiences per unit area.
Strength is a material's ability to withstand stress.
