Is there a minimum width to the vertical posts of a צורת הפתח?
Does the Lechi need to be strong enough to support a brick – אריח?
The מרדכי brings the opinion of the מהר”ם מרטנבורג that a vertical line of plaster 10 tefachim tall qualifies as a צורת הפתח. Why is this acceptable? A flat thin layer of plaster is not strong enough to support a door made out of straw which is qualification for the vertical posts a צורת הפתח?

Question:
The Gemara is very exacting with the mathematical calculation of the ratio of the circumference of a circle to the diameter (3:1) taking into consideration the thickness of the walls of the basin.
How could this be when the real ratio of the circumference of a circle to the diameter is pi (3.14:1)?
And תוספת יום טוב says since קורה is only required mdrabanan they are lenient even to consider the width of tefach even though it is a little narrower.
Very quickly review the גמרא דף יד. “ר’ יהודה אומר (three lines before the medium size lines) until “עגולה” (two dots – sixth line from bottom of the Amud)
Questions:
Why according to the Rabanan does a קורה which is four tefachim wide not need to be strong enough to support a brick?
Is a four tefachim wide קורה made from straw or twigs kosher?
According to the opinion of the Shulchan Aruch סע’ כב that two קורות combined can only be maximum one tefach apart from one another. Could they combine to create a קורה which is four tefachim wide and therefore be allowed to be 2 1/2 tefachim apart from one another ?
What if the physical material of the קורות total four tefachim but there are gaps in between?

Questions on the Gemara earlier on the Amud
The Gemara brought a scenerio where a mat is placed over a קורה and the mat is suspended in the air 3 tefachim or more from the ground. The קורה is disqualified because it is not visible and the mat does not serve as a mechitza since there is a gap of three tefachim between it and the ground.
According to the opinion of קורה משום מחיצה why should it matter that the קורה is not visible it should still function as a mechitza?
