INPUTS
Inputs: Band brake width
=
3.75 inches
Asbestos thickness
=
0.375 inches
Stainless steel band
=
0.500 inches thick
Brake Capacity = 18,000 lbs @ mid layer = 66.25 inches
Brake Capacity @ 51.25" radius (hub) =
18,000(66.25)
= 23,500 lbs
51.25
Assume:
a
= angular band contact
= 2700
f = friction coefficient
= 0.4
