AVERAGE NORMAL DEFORMATION IN THE BALLOON | MECHANICS OF MATERIALS

PROBLEM 2.1: The diameter of an air-filled rubber balloon is 150 mm. If the air pressure inside is increased until the diameter reaches 175 mm, determine the average normal strain in the rubber.

Average normal strain, also known as axial specific strain, is determined by the lengthening or contraction of a line segment per unit length, that is, the change in length from its initial length. In the case of the exercise in question in the video, the average normal strain is determined by increasing the circumference of the rubber balloon in relation to its initial length of the circumference.
𝜀 = ∆/L0 = (𝜋df - 𝜋d0)/𝜋d0
𝜀 = (df - d0)/d0
