To find the meter stick's mass you're going to need to make use of torque, which means you're going to need to know the center-of-mass of the meter stick. Ideally this would be at 50 cm but reality is rarely ideal. As such, you'll need to determine the center-of-mass of the meter stick. Go to the Center-of-mass section and record the needed data in the table below. Position uncertainty Center-of-mass position Hanger mass Mass uncertainty (cm) (cm) (g) (g) 49.87 0.07 Now it's time to set up the meter stick with the hanger as shown in the picture above. Go to each Trial (Trial 1 has instructions) section and record the needed data in the table below. Let the clamp be the rotational axis (as such, how much torque will FN create and why?) and then determine the values for the rest of the table. The formula for the meter stick mass uncertainty is given just below the table. Trial 1 Trial 2 Trial 3 Trial 4 Trial 5 Clamp position 51 (cm) X Hanger position (cm) Lever for meter stick weight (cm) Lever for hanger weight (cm) Meter stick mass (g) Meter stick mass uncertainty (g) meter stick mass uncertainty = (hanger mass uncertainty X hanger lever) + (hanger mass x position uncertainty meter stick lever Finally, determine your average value for the meter stick mass & uncertainty as well as the range (the range is based on the average & the uncertainty). Ideally, the mass values you calculated in each trial will fall within the range below. average meter stick mass = max average meter stick mass = min average meter stick mass =In this lab you will use equilibrium to determine the mass of a meter stick. To do this, a hanger (whose mass is known) will be hung on the meter stick and the meter stick will be carefully balanced (see the picture below). :2} '. g \"2137' To begin with, you should draw a force diagram for the meter stick in the above picture. Then answer the questions by stating the direction of each force and where each force is acting. Normal force: T c J at the fulcrum C J Tension force: No tension force 3 ,/ No tension force 3 J Meter stick weight: l c J at the meter stick's center of mass 0 ../ Hanger weight: 1 c J where the hanger is attached to the meter stick 0 J Netforce: Nonetforce 0 No netforce C \\/
