The changes in pressure cause a change in velocity (accelerations) resulting in motion if the balanced forces are maintained.
In choosing a rivet, it should be made of the same materials as the object being fastened, have an equal length to the thickness of the two objects, select non-corrosive ones, the diameter must fit the hole of installation, and have a countersunk head because of the wind resistance concern (Dorf n.p).
The modulus of elasticity is the rate of change of strain as a function of stress. Specifically, this is the slope of the straight-line portion of a stress-strain graph. Furthermore, it can be described as the mathematical description of an objects affinity to be distorted elastically when energy is applied to it (Fang 304). The application of force result in the formation of a stress-strain curve (slope) called the Modulus of Elasticity.
The plastic property of a material is the plastic deformation that occurs when there is adequate stress to deform a metal permanently. Specifically, it involves the movement of dislocation that breaks limited number of atomic bonds (Fang 307). On the other hand, elastic property or deformation is a temporal change in the shape of a metal at a little stress that allows the material to self-reverse to its original
