Question

Part 1: Three Levers In this part, you will set up a lever in three different configurations. First Lever The first is straightforward: set up the plastic ruler so that it pivots about its center. Apply two forces (resulting in two torques) to it as shown. Torque 1: Torque 2: Place a hanger (20 grams) in the first hole to the left of center and add 200 grams to it. Place a second hanger in the hole that is farthest to the right and add mass to it until the ruler is balanced. 1 = 5 cm = 0.05m 12 = a5 cm = 0.25_m mi = 2ao 8 = 0.22 kg m2 = 45 0.045 kg F1 = mig = N F2 = m28 = N T1 = r1 F1 sin(90°) = Nm T2 = 12 F2 sin(90°) = Nm Calculate the percent difference between the two torques: % difference = IT₂-Tal x 100 = T1 %

Just need help filling in the blanks! Thank you.
