Step 5: Find the distance r, and 12 from rc, record data in observation table below. Example: In figure below, r2 = - 20 + 50 = 30 cm, 1 = 87 - 50 =37 cm 20 30 50 60 70 90 Fulclrum F2=m28 F1=m18 Find force Find force F2 of the F1 of the hanging hanging mass mass Fig 1: Experimental set up Step 6: Find Force on each end of the ruler by substituting vales for m, and my in equation F1=mig and F2=m28 Step 7: Exchange weights mi and mz and repeat from step 4 Step 8: There is no step 8 Distance from Torque Sum of Mass (m) in Kg F = mg (N) Obs. # center of ruler T = Fr Torques (1g=0.001kg) g=9.8 m/s2 (1cm = 0.01m) T = 1+ 2 F1 ti = Fin m1 0.05 m 1 F2 12 = Fr2 m2 0.10 1= -_ _m F1 ti = Fr m1 0.10 m 2 F2 12 = Fr2 m2 0.05 12 = - m Is sum of torque zero?
