Problem $15\mathrm{.}081-$ The double gear rolls on the stationary left rack $R$

The double gear rolls on the stationary left rack $R.$ The rack on the right has a constant velocity of $2\mathrm{.}500f\frac{t}{s}.$

Problem $15\mathrm{.}081.$a $-$ The angular velocity of the gear

Determine the angular velocity of the gear. $($Round the final answer to three decimal places.$)$

The angular velocity of the gear is $ra\frac{d}{s}.$

Problem $15\mathrm{.}081-$ The double gear rolls on the stationary left rack $R$

The double gear rolls on the stationary left rack $R.$ The rack on the right has a constant velocity of $2\mathrm{.}500f\frac{t}{s}.$

Problem $15\mathrm{.}081.$b $-$ Instantaneous center of rotation involving parallel velocities

Determine the velocities of points A and $D.$

The velocity of point $A$ is $f\frac{t}{s}$uarr.

The velocity of point $D$ is $|f\frac{t}{s}4|$
