The Physics of Bending an iPhone

Let’s consider the worst case scenario.  Suppose you have skinny jeans on a super skinny leg.  The leg is so skinny that when you put the iPhone 6 Plus in your pocket, the fabric pulls straight down at a 90 degree angle to the phone.  In this case, you would need 125 N tension in the fabric to be equivalent to the iPhone test in the lab.  That’s only 28 pounds of tension, so you would think that would be ok.  But wait!  There are two problems.  First, some jeans can only take about 28 pounds of tension before ripping (not everything is Levi tough).  Second, the test at the Apple lab seemed to indicate that the iPhone could take an equivalent bending moment of 25 kg (250 N) at the center and that wouldn’t make it bend.  How much does it take to bend?  Who knows.
