Section 6: Agricultural Process Engineering

Engineering Properties of Agriculture Produce

Subtopic: Rheological properties

Question Statement:

The Maxwell model of viscoelasticity consists of:

Options:

  • (A) A Hookean spring and a Newtonian dashpot connected in series
  • (B) A Hookean spring and a Newtonian dashpot connected in parallel
  • (C) Two springs connected in parallel with a dashpot
  • (D) A Saint-Venant friction element in series with a spring

Answer Key:

A

Step-by-Step Solution & Explanation

Viscoelastic models: • Maxwell model: Spring (elastic) and dashpot (viscous) in series (illustrates stress relaxation). • Kelvin-Voigt model: Spring and dashpot in parallel (illustrates creep). • Burgers model: Maxwell and Kelvin-Voigt elements connected in series.
