aynamic load rating of the bearings?
6) The ball bearings in a large
agricultural drone need to have a
dimensionless life x = 50 under a
radial load F = 100 lbf at reliability
99%. What is the required dynamic
load rating of the bearings?
7) The ball bearings in an industrial
waffle-making robot have a dynamic
load rating of 2500 lbf. They need
to support a radial load of F = 1500
Ibf. At a reliability R = 75%, for how
many cycles can we expect them to
function?

8) A ball bearing in a tree shaker has
a dynamic load rating of c10 = 10
kips and a static load rating of c0 = 5
kips. It experiences a radial load Fr =
5 kips and an axial load Fa = 0.1 kips.
What is the equivalent radial load Fe?
9) A different ball bearing (c10 = 30
kips, c0 = 17.5 kips) in a different
part of the tree shaker experiences
a radial load Fr = 8 kips and an axial
load Fa = 2.975 kips. What is the
equivalent radial load Fe?
