Question

How can I find the % difference(weights)?

In Trials 1-3, you're given known positions, for the right hanger.? r You'll then adjust its hanger weight to achieve balance. 3 In Trial 1. the given value of 1.00 m in the first position column tells you to add a second clamp and mass hanger (well call g "Hanger 2") at 100 cm Then, following the successive value theoretically. by calculation. and then experimentally. For Trial 3. show your calculations of the weight retired to balance the beam. weight_left x lever arm_left = weight (predicted)_right times lever arm (given)_right weight (predicted)_right = .

Answer 1

Cl. Moments Anti-Cl. Moments Weight Theoretical Weight Experimental Trial Torque Position Lever arm % Difference 0.05 0.05 0.05 0.5 0.1 0.18 0.1 0.5 0.1 0.6 0.3 0 0.6 0.68 20 Note 1 Lever arm must be computable from position as x - (P-0.5),0.5 being the position of fulcrum in this case. x (obtained) must have values 0.1 and 0.18, which is causing the errors in Trial 1 and 2. Note 2 Note 3 Weight (Theoretical) must be computable from Lever arm as A T/x Note 4 Weight (Experimental)-B % Difference, (The error in weight computation in %) must be computable from the two weights A and B as (B-A)/A] x100 Note 5
