Chapter 20.3, Problem 10P

The electric fan is mounted on a swivel support such that the fan rotates about the z axis at a constant rate of ωz = 1 rad/s and the fan blade is spinning at a constant rate ωs, = 60 rad/s. If ϕ = 45° for the motion, determine the angular velocity and the angular acceleration of the blade.

5/125 The disk rotates with angular speed -2 rad/s. The small ball A is moving along the radial slot with speed L= 100 mm/s relative to the disk. Determine the absolute velocity of the ball and state the angle B between this veloc- ity vector and the positive x-axis. 125 mm
If the wheel in each case rolls on the circular surface without slipping, determine the acceleration of point C on the wheel momentarily in contact with the circular surface. The wheel has an angular velocity ω = 3.6 rad/s and an angular acceleration α = 5.0 rad/s2. The distances R = 1.5 m and r = 0.6 m.
The disk with radius r = 0.09 m is rotating at a constant angular velocity of ω = 0.9 rad/s (counterclockwise) about the fixed pin support at O. For the instant shown, find the relative acceleration component (aB/A)n, where (aB/A)n = {(ax)i+(ay)j} m/s2.  Choose the correct answer: a) ax=-0.292; ay=-0.0729 b) ax=0.786; ay=0.196 c) ax=0.292; ay=0.0729 d) ax=0.0182; ay=0.00349 e) ax=-0.786; ay=-0.196
