Question
If load $B$ has a downward velocity $v_{B},$ determine the upward component $\left(v_{A}\right)_{y}$ of the velocity of $A$ in terms of $b,$ the boom length $l,$ and the angle $\theta$. Assume that the cable supporting $A$ remains vertical.
Step 1
We have a boom with length $l$ and a load $B$ with downward velocity $v_{B}$. The boom is at an angle $\theta$ from the horizontal. The load $A$ is suspended from the boom and has an upward velocity component $v_{A}^{y}$. Show more…

The load $L$ is being elevated by the downward velocities of ends $A$ and $B$ of the cable. Determine the magnitude of the acceleration of point $P$ on the top of the sheave for the instant when $v_{A}=2 \mathrm{ft} / \mathrm{sec}$ $\dot{v}_{A}=0.5 \mathrm{ft} / \mathrm{sec}^{2}, v_{B}=3 \mathrm{ft} / \mathrm{sec},$ and $\dot{v}_{B}=-0.5 \mathrm{ft} / \mathrm{sec}^{2}$
