A balance and torque experiment is conducted with a balanced ruler (that is, the pivot point is in the middle). Length of the ruler: 1 m Mass of the ruler: 650 g Weight 1: 4 N. This weight is placed at the 15-cm mark on the ruler. Weight 2: 3 N. This weight is placed at the 58-cm mark on the ruler. We want to balance the ruler by supporting it with a spring scale at the 20-cm mark. What...
A balance and torque experiment is conducted with a balanced ruler (that is, the pivot point is in the middle). Length of the ruler. 1 m Weight of the ruler 8 N te of 1.00 Mass 1: 148 g. This mass is placed at the 44-cm mark on the ruler. What should be the magnitude of the second mass? Answer estion The second mass is to be placed at the 85-cm mark on the ruler. Check

In order to balance the lever (balance means zero net torque) shown as below horizontally, how much weight should we put in the middle (70 cm mark on the ruler) if the reading on scale hanged on the left side (95 cm mark on the ruler) is 300 grams? The hinge point is at 40 em mark on the ruler and the center of the ruler is right at 50 cm mark. The ruler's weight is 200 grams. Do not...
A ruler, balanced at its center point, has two coins placed on it, as shown in the figure. (Intro 1 figure) One coin, of mass M_1= 10g, is placed at the zero mark;the other, of unknown mass M_2, is placed at the 4.7 mark. The center of the ruler is at the 3.0 mark. The ruler is in equilibrium; it is perfectly balanced.[IMG]http://i40.tinypic.com/15cj2g9.jpg[/IMG]http://tinypic.com/view.php?pic=15cj2g9&s=5A)Does the pivot point (i.e., the triangle, in the diagram, upon which the ruler balances) exert a force...
A uniform ruler of 1-m length is supported using a knife-edge clamp at 20-cm mark. The ruler is balanced by hanging a 320-g weight at 5-cm mark along the ruler. What is the mass of the ruler? What the torque on the ruler due to the normal force from the clamp?
2 m Length of the ruler Weight of the ruler Weight 1 has the mass of Weight 1 is located at Total torque on the left side of the ruler Weight 2 is has the mass of Weight 2 has to be placed at 15 N 400 g 20 cm mark 1.3 kg
A 60 cm ruler, which has 10 g weight, is on the pivot at 19cm point of the ruler. The center of gravity for the ruler is at 29 cm point. You have a 20 g weight to balance the ruler. At what point of the ruler you will hang the weight to make the system equilibrium? (The ruler will not move on the pivot, one mass system) 19 cm @ 29 cm Ruler Length = 60 cm Ruler Ruler...
a simulation was used to recreate the lab.
Toys for a Torque Weighted Ruler 1. Set up a balanced weighted ruler system with two different known masses suspended in cradles at different positions on the same side of the meter stick, balanced by a third unknown weight, warunk on the other side, keeping the pivot at the center of the ruler. Weigh the hanging scales, clips, and masses. You will use torques to determine the weight of the unknown, Wink....
1.)In the static equilibrium experiment, a student placed the 107 g mass (including the hanger mass) at position of 6.6 cm from the fulcrum. Then, placed a 52 g mass (including the hanger mass) on the right side of the fulcrum and adjusted the position until balance is achieved. Calculate the torque (magnitude only) caused by the 107 g mass. (g = 9.80 m/s2) 2.)In the static equilibrium experiment, a student placed the 105 g mass (including the hanger mass)...
A meter stick is found to balance at the 50.0 cm mark when placed on a fulcrum. When a 0.100 kg mass is attached at the 10.0 cm mark, the fulcrum must be move to the 34.0 cm mark for balance. a) What is the mass of the meter stick? b) How much torque does the 100 g mass exert on the meter stick around an axis at the new fulcrum (at 34.0 cm) c) How much torque does the...
