16.81 The shutter shown was formed by removing one quarter of a disk of
0.75-in. radius and is used to interrupt a beam of light emanating from
a lens at C. Knowing that the shutter weighs 0.125 lb and rotates at the
constant rate of 24 cycles per second, determine the magnitude of the
force exerted by the shutter on the shaft at A.
16.82 A turbine disk weighing 50 lb rotates at a constant rate of 9000 rpm.
Knowing that the mass center of the disk coincides with the center
of rotation O, determine the reaction at O immediately after a single
