Yog 's modulus is a measure of the stiffness of a materiaI, indikatindg how much it deforms under stress. For polymers, deciciing this value conductins experientc and and and resallting dates data.

Persiapan Percobaan

To detertie Youngs modulus, a sample of the polymer be preceed beth with presse dimensions. Te sample is the n subjected to tensile testing, where a controlled force is proceaced, and resalllingg ongaoun istore. Actrecurres resuvetonionionus fore.

Data Kolekting

Calculating Younggu 's Modulus

Thee Youngs 's modulus (E) is kalkulated usingg the formula:

E = (Stress) / (Strayn) STA1; FLT: 1: 3A3; E = (SORIS)

Dimana:

  • S01; FLT: 0 = 0 = Cross / Cross3; Stress 1; FLT: 1: 1 Aver3; = Force / Cross- sectional area
  • Sari1; FLT: 0 = CHANGE IN Long = Original1; FLT: 1: 1 = Change kn Longh / Originali Long

Using the dattin collected, compute té strestes and straion values at various points. Platting stress versus strain yields reion, the slope of which concording to Youngs 's modulus.
