1.For each trial, calculate the distance between the pivot point and the string (r, in units of meters). Record your results in Table 1. Show your work for the first 3 trials below (for the rest of the trials, you can just fill in the table). 2.For each trial, calculate the magnitude of the torque on the meter stick due to the tension in the string, in units of Newton-meters (Nm). Use the formula τ = r F sinθ. Record your results in Table 1. Show your work for the first 3 trials below (for the rest of the trials, you can just fill in the table) 3.Find the average of all the torques you calculated in Table 1. Show your calculation and record your result below.

mark on the meter stick.
4. There is a hole in the meter stick that serves as the pivot point for this experiment. Measure
and record the position of the hole below.

cm
5. Slide the string to the 50 cm mark, and remove the pivot screw from the meter stick. Adjust
the position of the string until the meter stick is perfectly balanced. This is the position of the
center of mass of the meter stick. Record this position below.
center of mass position =
50.0
cm
6. Hold up the meter stick until the string goes slack, then zero the force probe. After the force
probe reading goes to zero, lower the meter stick back to its original position. The force
probe will now be measuring the weight of the meter stick. Record the weight below.
weight of meter stick =
