Review
The vacuum cleaner's armature shaft S shown in (Figure 1) rotates
with an angular acceleration of a = 4w3/4 rad/s², where w is in
rad/s.
Determine the brush's angular velocity when t = 5 s, starting from w₁ = 2.0 rad/s, at t = 0. The radii of the shaft and the brush are 0.35 in. and 1.3 in., respectively.
Neglect the thickness of the drive belt.
Express your answer in radians per second to three significant figures.
