Monkey or Weight: Which Will Reach the Top First?

In summary, the conversation discusses the question of whether a monkey or a weight will reach the top of a rope first, assuming a lossless pulley and weightless rope. The conversation mentions two key points to consider: the monkey momentarily increases the tension in the rope when climbing and the center of mass of the system cannot be raised or lowered due to no external forces acting on it.

A rope hangs over a pulley. On one side a weight is tied. The weight is resting on ground when a monkey of equal weight starts climbing up the other side of the rope. Will the monkey reach the top first or the weight? Assume the rope and pulley to be lossless and the rope weightless.

Well, what's your guess, and why?

We can NOT help you unless you show your work first. Please read the posting guidelines.

Consider 2 things:
1) when the monkey pulls on the rope he momentarily increases the
tension in the rope.

2) since no external forces act on the system of monkey and weight
the center of mass of the two cannot be raised or lowered.
 

1. How does a monkey, pulley, and weight system work?

In this system, the monkey represents the effort or force applied, the pulley represents the fulcrum or pivot point, and the weight represents the resistance. The monkey pulls down on one side of the pulley, causing the weight to be lifted on the other side.

2. What is the principle behind using a monkey, pulley, and weight system?

The principle is based on the concept of work and energy. The monkey's effort is transferred to the weight through the pulley, allowing the weight to be lifted with less effort than if the monkey were trying to lift it directly.

3. Can a monkey, pulley, and weight system be used to lift heavy objects?

Yes, this system is commonly used to lift heavy objects in many industries such as construction, transportation, and manufacturing. By using multiple pulleys and increasing the number of ropes, the weight can be distributed and lifted more easily.

4. Are there any limitations to using a monkey, pulley, and weight system?

One limitation is that the weight being lifted must be less than the combined strength of the monkey and the pulley system. Additionally, the system may become less efficient when used to lift objects that are too heavy or have irregular shapes.

5. What are the advantages of using a monkey, pulley, and weight system?

This system allows for the lifting of heavy objects with less effort and strain on the monkey. It also allows for precise control and movement of the weight. Furthermore, the system can be easily modified and adjusted to fit different needs and situations.
