●
Pulley A has an angular acceleration given by a = 0.60 (rad/s?), where is
measured in radians. If said pulley has an initial angular velocity of 2.9 rad/s
when 0 = 0
and s=0, determine the velocity of block B, in m/s, when it has been raised a
height s = 0.7 m.
Pulley C and drum D are rigidly attached.

Expert Solution

Step 1

Write the given data with suitable variables.

$\begin{array}{rcl} α_{A} & = & 0.6 r a d / s^{2} \\ ω_{A 1} & = & 2.9 r a d / s \\ h & = & 0.7 m \\ r_{A} & = & 50 m m \\ r_{C} & = & 150 m m \\ r_{D} & = & 75 m m \\ s & = & 0.7 m \end{array}$
