The ground
supports are significant as they form the contact between the pallet and
the floor of the cargo hold.
The contact
area is 0.2m x 2m twice or 0.8 square metres.
There are
3.28 x 3.28 = 10.76 square feet in a square metre so 0.8 square metres is 0.8 x
10.76 = 8.61 square feet.
The maximum
load distribution is 68kg per square foot so the maximum load on the pallet is
68 x 8.61 = 585.3kg, 285.3kg more than the present load.
