A box attached to a pulley on a ramp

In summary, the conversation is discussing a box on an incline with a mass of 27.0 kg and a bucket attached to a pulley with a mass of 25.0 kg. The incline has a 35 degree angle and there is static friction of 0.650 and kinetic friction of 0.490. The questions being asked are about the applied force on the box, the friction exerted on the box by the ramp, if the box remains at rest relative to the ramp, and the net acceleration on the box. The attempted solution mentions that the applied friction is 152N and the friction force is 93N, but the full question is needed to find the rest of the solution.

Homework Statement


Mass of box: 27.0 kg
mass of bucket attached to pulley: 25.0 kg
incline:35 degrees
static friction:.650
kinetic friciton: .490

Okay, there is a box on an incline. The box is attached to a pulley. A bucket is attached to the other end of the pulley. The bucket is going straight down
Its actually a few questions. What is the applied force on the box? What is the friction exerted on the box by the ramp? Does the box remain at rest relative to the ramp? What is the net acceleration on the box?



The Attempt at a Solution


Okay i figured out that the applied friction is 152N. and the friction force is 93N (i think).
I just know where to start to find the rest.

It would be easier to have the full question.
 

1. How does a pulley on a ramp work?

A pulley on a ramp is a simple machine that uses a rope or cable wrapped around a wheel to change the direction of a force. The weight of the box attached to the pulley creates a downward force, which is then transferred to the ramp through the pulley, allowing the box to move up or down the ramp.

2. What is the purpose of a box attached to a pulley on a ramp?

The box attached to a pulley on a ramp is used to demonstrate principles of physics, such as force, work, and energy. It allows for a hands-on exploration of how forces and simple machines work together to move objects.

3. How does the incline of the ramp affect the movement of the box?

The incline of the ramp affects the movement of the box by changing the amount of force required to move the box. A steeper incline will require more force to move the box, while a gentler incline will require less force.

4. What factors can affect the efficiency of a box attached to a pulley on a ramp?

The efficiency of a box attached to a pulley on a ramp can be affected by several factors, including the friction between the ramp and the box, the weight of the box, and the angle of the ramp. Additionally, the condition of the pulley and rope can also affect the efficiency of the system.

5. How does the addition of weight to the box affect the movement on the ramp?

The addition of weight to the box will increase the downward force on the ramp, making it more difficult to move the box. This will require more work and energy to move the box up the ramp. However, the addition of weight can also increase the amount of force transferred through the pulley, making it easier to move the box in some cases.
