Mesh Weighing scale

MESH WEIGHING SCALE

INTRODUCTION 

Designed and developed a new weighing machine known as Mesh weighing scale. It consists of a plastic sheet in tension. When mass is placed on the sheet, the sheet distorts. The distortion is measured by a suitable scale; this reading is proportional to the object’s mass.

APPARATUS:

Mesh made of plastic, 4 poles, base, linear weights and ruler.

APPARATUS DESCRIPTION:

Mesh: It’s a plastic sheet 5’x5’.

Poles: They’re 4’ long rods which hold the plastic sheet. These rods are glued to the base.

Conical tops: They’re glued on top of the poles so as to hold the sheet. The sheet is never glued due to the need of replacing them frequently.

Ruler: It’s a linear rod which is calibrated to measure the distortion in the sheet.

Linear Weights: Any weight that’s roughly linear.

PROCEDURE:

The apparatus is arranged as shown in the picture. The weight needs to be placed perfectly linear near the ruler.

MEASUREMENT:

The weight bends the plastic sheet which in turn moves and coincides with the ruler. We can make an approximate measurement using this method. Any linear weights can be measured; they need not be perfectly linear like rectangular rod. We can measure mass of pencil, pen, toothpaste tube, etc. Note that the plastic sheet must be replaced after certain measurements as it can give wrong readings since plastic loses its small elastic strength to return back to its initial position. 

CONCLUSION:

Thus we can measure linear weights easily using this equipment without using electricity!!!
