Q:imagine with mei want one side to be plastic to see whats happening insideand the other 3 sides is iron sheetits a straight duct ,,, no anglesvolume of the duct = 0.35 x 0.35 x 2.5a professor told that the best thickness for plastic side is 3mmand the iron sheet is 0.6mmis that right??if it is wrong tell me the best thickness for both??

would increase the thickness

Q:When was the last time you broke out the plastic sheets?

last week

Q:My doxie puppy is 7mo and chews on everything under the sun. While at work today the got the lid of a candle and a dryer sheet. usually unsupervised everything is put up or away to avoid these things happening but I have no Idea where she got it from but either way. she chewed the plastic around the lid off and I found most of them but I think she swallowed a few. Six hours later the threw up clear liquid and it had a two very small spots of blood and I mean so small almost specks. She is still eating drinking and humping my arm so I asume she is ok for the moment but I was just wondering if I should be overtly worried. thank you!

I think it is a good idea to invest in a crate and some bitter apple spray. I have a 8 month old and a 2 year old English setter and I would not even dream of leaving them out of their crates when nobody is home. The 8 month old barely stays out of trouble when people are watching her.

Q:Can plastic sheets be used for soundproofing?

Yes, plastic sheets can be used for soundproofing to some extent. They can help reduce sound transmission by acting as a barrier and absorbing some of the sound waves. However, the effectiveness of plastic sheets alone in soundproofing is limited compared to other specialized soundproofing materials.

Q:How do you clean plastic sheets?

To clean plastic sheets, start by wiping off any loose dirt or debris with a soft cloth or sponge. Then, mix a mild detergent with warm water and gently scrub the sheets using a soft brush or cloth. Rinse thoroughly with clean water and allow them to air dry. Avoid using harsh chemicals or abrasive materials that can damage the plastic.

Q:Are plastic sheets resistant to cracking from heavy loads?

Yes, plastic sheets are generally resistant to cracking from heavy loads. They have high tensile strength and flexibility, allowing them to withstand significant pressure without breaking. However, the specific type of plastic and its thickness can influence its resistance to cracking.

Q:Hi all,I would like to know how to calculate the maximum volume of a bag made from 1 folded plastic sheet of which the outer edges are welded together. Say the bag is 1 m x 2 m. If I inflate that bag, the volume will increase until it reaches a maximum. Does somebody know how to calculate the maximum volume? Thanks

I don't know, and this is an approximation. Suppose the center cross-section of the bag (1 meter from each end) inflates to where it is perfectly circular. The diameter of the circle will be (2 m)/pi = 0.6366 m. Near the ends of the bag, the cross-sections parallel to this center cross-section might be very narrow ellipses; and exactly at the ends of the bag, the X-section is 0. Let's suppose the semi-minor axis of each ellipse decreases linearly from 0.3183 m to 0 unifomly as you move along the long axis of the bag. Note that you will not get 1 full meter away from the central X-section, because the section looking sideways at the 2-m seam is a rhombus of perimeter 4m, and its minor diagonal is 0.6366 m. Then the full length of the inflated bag would be 2 sqrt(1^2-0.3183^2) = 1.896 m. So I'm going to assume every cross-section parallel to the circular cross-section is an ellipse, whose semi-minor axis varies linearly from 0.3183m down to zero, and whose semi-major axis varies linearly from 0.3183m up to 0.5m. In particular, taking x=0 to be the coordinate of the circular X-section, I have b = 0.3183 - (0.3183/0.948) x, and a = 0.3183 + (0.1817/0.948) x. The area of each ellipse is pi*a*b, and the volume of the bag is 2 times the integral from x=0 to x=0.948 of pi ab dx = 2*int from x=0 to x=0.948 of pi [0.3183 - (0.3183/0.948)x] [0.3183 + (0.1817/0.948)x ] dx = 2 * int from x=0 to x=0.948 of pi [0.1013 - (0.3183/0.948)(0.1366 x) - 0.06435x^2 ] dx = 2 * int x=0 to x=0.948 of pi [0.1013 - 0.04586 x - 0.06435 x^2] dx After integration you have 2*pi [0.1013x - 0.02293 x^2 - 0.02145 x^3] to be evaluated at x=0 and x=0.948 meters = 2 pi [0.096 - 0.0206 - 0.0183] cubic meters = (6.28)(0.057) = 0.36 cubic meters Another figure for comparison is a prolate ellipsoid whose minor semi-axes are both 0.3183 and whose major semi-axis is something like 0.9; its volume would be pi*a*b*c = 0.29 m^3. So, my first answer probably isn't completely crazy...

Q:Can plastic sheets be glued together?

Yes, plastic sheets can be glued together using various methods such as solvent-based adhesives, epoxy, or even heat welding. The choice of adhesive will depend on the type of plastic being used.

Q:How to check the depth of plastic drainage plate inserted into soil

The main use of the long fiber non-woven membrane is hot, water resistant performance is strong, and good permeability, section size and drainage plate is relatively small, therefore, will not cause a great disturbance on the foundation in the construction;

Q:Can plastic sheets be used for protective barriers against COVID-19?

Yes, plastic sheets can be used as protective barriers against COVID-19. They can serve as physical barriers to prevent the transmission of respiratory droplets, which are one of the primary modes of COVID-19 transmission. Plastic sheets can be installed in various settings such as offices, retail stores, and healthcare facilities to create a physical barrier between individuals, reducing the risk of exposure to the virus. However, it is important to note that plastic sheets alone are not sufficient to prevent the spread of COVID-19, and they should be used in conjunction with other preventive measures such as wearing masks, practicing good hand hygiene, and maintaining social distancing.
