The length of the bar is .900 m, its mass is .700 kg, and its center of mass is .

The figure below shows a bar attached to a pivot p with a calibrated spring attaching the bar to the ceiling. The length of the bar is .900 m, its mass is .700 kg, and its center of mass is .400 m from the pivoted end. Please use (|)=60.0 degrees, theta=75.0 degree, g=9.80 m/s^2, and calculate horizontal and vertical components of the force the pivot exerts on the bar and the tension in the calibrated spring connecting it to the ceiling.
