What is the formula to calculate the thickness of a test tube?​

Physics
1 answer:
Maslowich2 years ago
4 0

Answer:

Having the inside dimensions (ID) and the outside dimensions (OD) will allow you to figure out the wall thickness on tubing. You would need to subtract the ID from the OD and then divide by two. This number is the wall thickness.

vagabundo [1.1K]

Answer:

Precipitation amounts

Explanation:

Meteorologists are scientists whose job is to predict different weather weather conditions. They study the atmosphere of the earth thoroughly so as to make a clear and concise weather forecast.

Meteorologists makes it possible for people to get information on possible rainfall or sunshine, it also enable people to know about a possible hurricance occurrence.

Meteorologists make use of a variety of tools to predict the weather, they include: wind vanes, barometers, anemometers, rain gauges, thermometer, hydrometer, Campbell Stokes Recorder,Transmissometer.

A wire of length 5mm and Diameter 2m extends by 0.25 when a force of 50N was use. calculate the
bazaltina [42]

Answer and Explanation:

Data provided in the question

Force = 50N

Length = 5mm

diameter = 2.0m = 2\times 10^{-3}

Extended by = 0.25mm = 0.25\times 10^{-3}

Based on the above information, the calculation is as follows

a. The Stress of the wire is

= \frac{force\ applied}{area\ of \ circle}

here area of circle = perpendicular to the are i.e cross-sectional  i.e

= \frac{\pi d^{2}}{4}

= \frac{\pi(2\times 10^{-3})^2}{4}

Now place these above values to the above formula

= \frac{4\times 50}{\pi\times 4 \times 10^{-6}} \\\\ = \frac{50}{\pi}

= 15.92 MPa

As 1Pa = 1 by N m^2

So,

MPa = 10^6 N m^2

b. Now the strain of the wire is

= \frac{Change\ in\ length}{initial\ length} \\\\ = \frac{0.25\times 10^{-3}}{5}

= 5 \times 10^{-5}
