A regulation tennis ball is made of an elastic material and can be modeled as a sphere. The center of the tennis ball is hollow, filled with pressurized air. You may assume the mass of air inside the tennis ball is negligible. The elastic portion of the tennis ball has a mass of 58 grams [g]. The outer diameter is 2.6 inches (in] and elastic material has a thickness of 3 millimeters (mm). What is the specific gravity of material used to form the tennis ball?

Material Properties

Construction in civil engineering demands high strength, durability, and longevity. These targets can be achieved by better design and analysis, along with the correct choice of materials. Different materials have different properties and hence, they respond and performs differently under the various condition of external loadings. It is therefore a critical task of an engineer to select the right material based on the property that the material is supposed to function in real-time. When speaking about the property, there are different categories of material properties like chemical property, physical property, mechanical property, electrical property, magnetic property, thermal property, etc. These material properties form the basis of material selection in various applications.
