Engineering Mechanics - Dynamics Chapter 16 Problem 16-11 The disk is originally rotating at angular velocity ω 0 . If it is subjected to a constant angular acceleration α , determine the magnitudes of the velocity and the n and t components of acceleration of point B just after the wheel undergoes a rotation θ . Given: rev 2 π rad = 6 rad s 2 = r 1.5 ft = 0 8 rad s = 2 rev = Solution: ωω 0 2 2 αθ + = 14.66 rad s = v B r = v B 22 ft s = a Bt r = a Bt 9 ft s 2 = a Bn r 2 = a Bn 322 ft s 2 = *Problem 16-12 The anemometer measures the speed of the wind due to the rotation of the three cups.

Unformatted text preview: t 1 a wind gust causes the cups to have an angular velocity = ( At 2 + B ) , determine (a) the speed of the cups when t = t 2 , (b) the total distance traveled by each cup during the time period t 1 , and (c) the angular acceleration of the cups when t = t 2 . Neglect the size of the cups for the calculation. Given: t 1 3 s = t 2 2 s = r 1.5 ft = A 2 1 s 3 = B 3 1 s = 402...
