A fulcrum is placed at the 55 cm position of a 100 cm (1 meter) stick with a mass of 18 kg. a 10 kg mass is placed at 70 cm position. where must a 5 kg mass be placed so that the net torque is zero? (assume the mass of the meter stick is uniformly distributed)

Expert Solution

Use the rotational equilibrium of stick about the fulcrum to find the position of the 5 kg mass on the stick as shown below.

The center of gravity of the meter stick is 49 cm. mass of meter stick 50 g . mass of hanger #1 =5 g. mass of hanger #2 = 5 g. 1.Place the fulcrum at 51 cm. Attach a 200 g mass, plus hanger #1, at 17 cm on the meter stick and calculate where to attach a 200 g mass, plus hanger #2, to balance it. 2.Balance the stick with the fulcrum at its center of gravity. Attach a...

1) A meter stick is placed in a support stand and balanced at its center of gravity. A 50 gram mass is placed at the 25.00 cm mark.

1) A meter stick is placed in a support stand and balanced at its center of gravity. A 50 gram mass is placed at the 25.00 cm mark. An unknown mass is placed on the other side of the meter stick and moved until the entire system is balanced. If the unknown mass is placed at the 75.00 cm mark, then what is the value of the unknown mass? Ignore the mass of the knife-edge clamps and assume that...

The figure shows a meter stick lying on the bottom of a 100-cm-long tank with its zero mark against the left edge. You look into the tank at a 30 angle, with your line of sight just grazing the upper left edge of the tank. a. What mark do you see on the meter stick if the tank is empty? b. What mark do you see on the meter stick if the tank is half full of water? c. What...

A meter stick on a horizontal frictionless table top is pivoted at the 80-cm mark. A force F1 = 5 N is applied perpendicularly to the end of the stick at 0 cm, as shown. A second force F2 (not shown) is applied at the 100-cm end of the stick. The stick does not rotate. a) What is the torque (magnitude and sign) about the pivot from F1? b) Explain why the torque from the pivot about itself is zero....

You attach a meter stick to an oak tree, such that the top of the meter stick is 2.47 meters above the ground. Later, an acorn falls from somewhere higher up in the tree. If the acorn takes 0.271 seconds to pass the length of the meter stick, how high above the ground was the acorn before it fell, assuming that the acorn did not run into any branches or leaves on the way down? acorn's height: _______m

PART 1 You have three tasks. Trial I: Balance the stick with the fulcrum at its center of gravity. Attach a 200 g mass, plus hanger #1, at Location A on the meter stick and calculate where to attach a 200 g mass, plus hanger #2, to balance it. Trial II: Balance the stick with the fulcrum at its center of gravity. Attach a 500 g mass, plus hanger #1, at Location B and determine where to attach a 200 g mass,...
