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.

Need help! Image attached. 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?
The air resistance to the motion of a vehicle is something important that engineers investigate. As you may also know, the drag force acting on a car is determined experimentally by placing the car in a wind tunnel. For a given car, the experimental data is generally represented by a single coefficient that is called the drag coefficient. It is given by the relationship: Fa C, = where C, = drag coefficient F, = measured drag force (Ib) p = air density (slugs/ft') V = air speed inside the wind tunnel (ft/s) A = frontal area of the car (ft²) What is the appropriate unit for C, if the preceding equation is to be homogeneous in units?

An Atwood's machine was used by a student to determine the acceleration of two masses, m₁=73 grams and m2=70 grams. The pulley rotates freely, and the masses were released from rest and the vertical distance traveled by the masses is 80 cm. The student conducted 5 trials to measure the time it took the masses to travel the vertical distance of 80 cm. The measured time were 3.23 s, 3.08s, 3.43s, 3.29s and 3.67s. If the mass of the pulley is 95.74 grams determine: a. The experimental value of the acceleration b. The true value of the acceleration c. the percent difference between the experimental and true values of acceleration.
