Elasticity, Stress, and Strain of Materials

Elasticity and Oscillations

In this course, Professor Giles Hammond (University of Glasgow) explores elasticity and oscillations. In the first mini-lecture, we consider elasticity, stress, and strain of materials when forces are applied. In the second mini-lecture, we use the simple pendulum to discuss oscillations and the corresponding displacement, velocity, and acceleration equations of the oscillating motion. In the third mini-lecture, we introduce the concept of simple harmonic motion and use two systems, the simple pendulum and a mass on a spring, to understand it’s properties. In the fourth mini-lecture we discuss damping and resonance. In the fifth mini-lecture, we bring together what we have learned in an example that covers stress, extension, and oscillation frequency of a steel wire.

Elasticity, Stress, and Strain of Materials

In this mini-lecture, we discuss how applying forces to an object can cause the object to distort. In particular we consider: (i) forces on bodies that cause bending, extension, and compression; (ii) the stress and strain on an object; (iii) the Young’s Modulus; (iv) stress-strain curves; and (v) high speed footage of a metal bar failure.
