I NEED $2$ ANGLES!!! The uniform bar has a mass of $45$ kg $.$ The spring has an unstretched length when theta$=90^($@$).($Figure $1)$

Figure

The figure shows a bar left end A $,$ which is on the ho

theta with the horizontal and has a length of $4$ mete

the horizontal surface. The stiffness of the spring is $4$

Part A

Determine the angle theta for equilibrium.
