Problem $16\mathrm{.}015-$ The tensions in the vertical ropes

At the instant shown the tensions in the vertical ropes $AB$ and $DE$ are $300$ N and $200$ N $,$ respectively.

Problem $16\mathrm{.}015.$d $-$ Angular acceleration of ropes

Knowing that the mass of the uniform bar $BE$ is $5\mathrm{.}400$ kg $,$ at this instant, determine the angular acceleration of each rope.

The angular acceleration of each rope is $*ra\frac{d}{s^2}$
