Data Table A Mass of meter stick (kg) Mass of hanging mass (kg) Center of mass of meter stick (m) Angle of String (9) Tension
Data Table A Mass of meter stick (kg) Mass of hanging mass (kg) Center of mass of meter stick (m) Angle of String (9) Tension in the string (N) y-component of Tension (N) x-component of Tension (N) Distance from pivot to string (m] Distance from pivot to the hanging mass (m) Distance from the pivot to the center of gravity of meter stick (m] Data Table B Torque caused by hanging weight about the pivot Torque caused by meter stick about the pivot Torque caused by string about the pivot Total clockwise torque Total counter clockwise torque Average of the total counter clockwise torque and total clockwise torque Percent Difference Data Table C Horizontal pivot force (N) Vertical pivot force (N) Magnitude of pivot force (N) Angle of pivot force (]1. Calculate the clockwise torques about the pivot caused by the hanging mass and the meter stick and record them in Data Table B. 2. Calculate the counter clockwise torque about the pivot caused by the tension in the string and record it in Table B. (Don't forget to account for the angle!) Calculate the total counter clockwise torque and record it in Table B. 3. Compare the total clockwise torque to the total counter clockwise torque by calculating the percent difference. Record the percent difference in Table B. 4. Calculate the known horizontal forces to determine the unknown horizontal pivot force and record it in Table C. 5. Calculate the known vertical forces to determine the unknown vertical pivot force and record it in Table C. 6. Calculate the magnitude and direction of the force at the pivot and record it in Data Table C. Show your computation
