$4/19$Review I Constants I Periodic Table

The figure $($Figure $1)$ shows a model of a crane that may be mounted on a truck.A rigid uniform horizontal bar of mass $m_1=85\mathrm{.}0kg$ and length $L=5\mathrm{.}40m$ is supported by two vertical massless strings. String $A$ is attached at a distance $d=2\mathrm{.}00m$ from the left end of the bar and is connected to the top plate. String B is attached to the left end of the bar and is connected to the floor. An object of mass $m_2=2000kg$ is supported by the crane at a distance $x=5\mathrm{.}20m$ from the left end of the bar.

Throughout this problem, positive torque is counterclockwise and use $9\mathrm{.}80\frac{m}{s^2}$ for the magnitude of the acceleration due to gravity.
