1. Select the correct material by elasticity
For this project, you can select any five to ten elastic
materials. Find those materials' elasticity and do a comparison study of any
specific purpose for instance which wood is best to construct a house and which material is used to uplift the object of any device.
The materials characteristics study is definitively useful for all sects of scientific developments. Every material has more physical and chemical characteristics, if we determine those characteristics we
can create the best device.
Materials
As you wish to select any type of five to ten elastic raw
materials. Like wooden or rubber. As usual apparatus microscope and telescope
are needed.
Methods
There are many methods that you can able to do in your
lab. Because of these methods are very common and simple for physics labs.
Pin and microscope method, single optic lever, Koenig’s
method, cornu’s method-elliptical fringes. All these methods are uniform and
non-uniform bending methods using with travelling microscope and telescope.
You can select any of the best methods at your convenience.
Apparatus selection and method selection are important for finishing a project
because of wrong method or apparatus selection will disturb your conclusion of the project.
Tabulated all experimental readings that you have done and gave a
strong comparison study of materials. The difference in values is essential to this project.
Of course, you can select one method for different materials or
two different methods to select different materials but you can measure all
materials and tabulate them.
Observation and measurement are important for accuracy.
2. Select the correct liquid
by surface tension
The surface tension of liquids is used to determine the liquid’s
spreading capacity. Because we should know about the liquid's surface tension
for its applications. For this project, you can select any five to ten liquids
like water, milk, petrol, soup oil etc. using these types of liquids to complete the
surface tension study.
Otherwise, you can select any specific liquids such as washing
powder making and washing soup making for which liquid has low surface
tension because of which liquids having low surface tension that liquid is
spread over the surface.
Mercury having 0.470 Nm-1 at room temperature is a high surface tension value but soap solution is 0.02-0.04Nm-1
surface tension only a low level of surface tension. So low level of surface
tension soap solution is spread over the surface but high surface tension
mercury can’t spread over the surface.
We select either low-surface-tension usage liquids or high-surface-tension usage liquids for our project studies.
Materials
You needed any five to ten liquids, a travelling microscope and
some other weighing instruments.
Methods
There are many methods for surface tension measurement. You can
select the drop weight method and capillary rise method. Both are easy to take
measurements for surface tension.
Measure all liquid’s surface tension and tabulate its
values. Compare all liquid's values of surface tension for your particular
liquid usage application. It is just like shampoo or soap oil of low surface
tension. Otherwise engine oil selection of high surface tension.
The selection of a theme is very important for exposing your project
because that theme is taking a vital role in the easiest project methods.
