Problem $16\mathrm{.}018.$b $-$ Force at pins

The motor at A causes the support beam $AB$ to have an angular velocity of $10$ rpm and zero angular acceleration at $=60.$ At this instant, determine the vertical components of the forces exerted on platform $BD$ by the pins at $B$ and $D.$

The vertical component of the force exerted by pin $B$ is $$ b$.$

The vertical component of the force exerted by pin $D$ is $$ b$.$
