Problem $15\mathrm{.}058.$b $-$ Angular velocity of the bar

For each of these values of $,$ determine the corresponding value of the angular velocity of bar $BD.$ Take $r_A=2\mathrm{.}800in.$ and $l_{BD}=10in.$

The corresponding value of the angular velocity of bar $BD$ for $=22\mathrm{.}9$ is $ra\frac{d}{s}$

The corresponding value of the angular velocity of bar $BD$ for $=192\mathrm{.}6$ is $|$ rad$/$s
