Essay On Stress And Strain
Several mechanical properties of materials that are important in design are ascertained by applying tension, compression or shear load on the material. Of the three, the most common mechanical stress-strain tests are performed in tension (Callister, 1997). When performing tensile tests, the load and elongation are measured in relation to the cross-sectional area or original length of the material (before the elongation). These geometric factors are normalized to the respective parameters of engineering stress and engineering strain. When a specimen…...

Best Balloon Car Design
In creating our balloon car, we used many physics principals to change the designs until we had a well performing car. The different principals helped us to change certain aspects of our car so that every part worked well together. The principal that with every action there is an equal and opposite reaction is what we used for the thrust of our car. We based our wheels on what ones caused the least friction. We used the fact that vertical…...

Distillation Lab Report
If the boiling points are too close, this method will not work because the two compounds will begin evaporating at close temperatures and will condense down to the receiving flasks at relatively the same times. This will not create an ideal separation. The apparatus used for this type of distillation is longer than that of a simple distillation experiment because this kind of apparatus creates more efficient separation. This happens because the fractional distillation apparatus is longer, and allows for…...

Effect Of Air Conditioner On Global Warming
Air Conditioning and Global Warming Air conditioning systems use energy to remove heat from a given location, transferring it to the exterior in the form of exhaust. Some of the energy is invariably wasted as heat, and this additional heat must also be exhausted. Thus, air conditioning results in net heat release to the environment. The warming effect is aggravated, moreover, because higher forms of energy such as electricity are used to power air conditioners. Generating and transmitting this electricity…...

Wheel And Axle Lab Report
Now for a rolling wheel the kinetic energy has two monuments, translational due to the bodily movement of the mass centre down the slope and rotational due to the wheel spin. Now the source of this energy is the loss in potential energy as the wheel moves down the slope. If it is reasonable to assume that friction effects are insignificant then no energy is lost. Thus the loss in potential energy becomes a gain in kinetic energy.Essay Example on…...

Assuming that pressure does not change, if you double the absolute temperature of a gas it causes the volume of that gas to double. Temperature and volume are proportional. The volume of a gas increases by 1/273 of its volume at CO for every degree Celsius that the temperature increases. This relationship happens because while the gas molecules are moving around in their container in different directions and peed, they will have an average amount of energy that is the…...

Stress
Stress is the loading applied on the material while strain is the deformation that results due to application of load or stress. By this definition, it is obvious that stress and strain are related and that relationship can best be explained by considering a stress-strain curve (Figure 1). Building materials have their own corresponding stress-strain curve which can be obtained by recording the amount of deformation (strain) upon application of tensile or compressive loading. Curve results reveal the behavior or…...
