Concept explainers

Center of Gravity of a system

The centre of gravity is a property that is based on the geometry of a rigid body or any particle. It is described as an equilibrium point or a hypothetical location where the total weight of the body is concentrated.

Review Conceptual Example 7 before starting this problem. A uniform plank of length 5.0 m and weight 225 N rests horizontally on two supports, with 1.1 m of the plank hanging over the right support (see the drawing). To what distance x can a person who weighs 462 N walk on the overhanging part of the plank before it just begins to tip? 41.1 ma
The 3.8 m long board shown in the image has a mass of 6.4 kg. The left support is 0.40 m from left end of the board. The right support is 1.2 m from the right end of the board. The cat has a mass of 5.0 kg and starts walking to the right. How far from the right support can the cat walk before the board tips over? (Give your answer in m.) Hints: There are two possible ways to solve this problem 1) Use the center of mass: Find the cat's position when the entire system's center of mass is at the right support. 2) Use torque: Set the pivot point at the right support and find the torque due to the weight of the beam and the weight of the cat. Answer:
A uniform 35.0-kg beam of length ℓ = 5.00 m is supported by a vertical rope located d = 1.20 m from its left end as in Figure P8.8. The right end of the beam is supported by a vertical column. Find (a) the tension in the rope and (b) the force that the column exerts on the right end of the beam.
4. A 5.0 kg cat and a 2.0 kg bowl of tuna are at opposite ends of a 4.0 m long seesaw. How far to the left of the pivot must a smaller 4.0 kg cat stand to keep the seesaw balanced horizontally? 2.0 m 2.0 m

Two kids are on a uniform seesaw supported at its center. The kid is on the right side of the seesaw has a mass m kg and is at a distance 1.59 from the center of the seesaw. The kid is on the left side of the seesaw has a mass 30.8 kg and is at a distance 1.49 from the center of the seesaw. The seesaw is in static equilibrium. What is the mass m in kg? Give your answer to three significant figures.
