Quick & Easy Problem: Pushing Box Up Ramp

  • Thread starter Tom McCurdy
  • Start date
In summary, the conversation was about calculating the work done when pushing a box up a ramp with a given horizontal force and angle. The magnitude and direction of the normal force, friction force, and force working against gravity were also discussed. The net force, work done against friction and gravity, and work done in giving the box kinetic energy were also mentioned.

Alright I am just trying to get a concept for a problem that I am doing

If you have a horizontal force of say X pounds and you want to push a box up a ramp that has a length of L with and angle of theta. How much work would you have done if you push the box the full length of L up the ramp?

What is the magnitude and direction of the normal force? What is the magnitude and direction of the friction force? What is the magnitude and direction of the force working against gravity? What is the net force? What is the work done against friction? What is the work done against gravity? What is the work done in giving the box kinetic energy?

sorry guys

Radian mode on the calculator instead of degree
 

FAQ: Quick & Easy Problem: Pushing Box Up Ramp

1. How does the angle of the ramp affect the force needed to push the box up?

The angle of the ramp affects the force needed to push the box up because as the angle increases, the component of the force acting against the box's weight decreases. This means that less force is needed to overcome the weight of the box and push it up the ramp.

2. What is the relationship between the mass of the box and the force needed to push it up the ramp?

The relationship between the mass of the box and the force needed to push it up the ramp is directly proportional. This means that as the mass of the box increases, the force needed to push it up the ramp also increases.

3. How does the friction between the box and the ramp affect the force needed to push it up?

The friction between the box and the ramp affects the force needed to push it up because friction acts in the opposite direction of motion. This means that the more friction there is between the box and the ramp, the more force is needed to overcome it and push the box up the ramp.

4. How can we calculate the force needed to push the box up the ramp?

The force needed to push the box up the ramp can be calculated using the formula F=mgsinθ, where F is the force needed, m is the mass of the box, g is the acceleration due to gravity, and θ is the angle of the ramp.

5. What other factors besides the angle of the ramp can affect the force needed to push the box up?

Other factors that can affect the force needed to push the box up include the mass and shape of the box, the surface of the ramp (smooth vs rough), and the force of friction between the box and the ramp. Additionally, external forces such as wind or an incline on the ramp can also affect the force needed.
