Can't find normal and tension force

In summary, there are two problems where the individual forces need to be found. The first problem involves finding the normal force using the formula Fnet = Fnorm-Fgrav. The second problem also requires considering the directions of the forces in order to find the tension force.

i have two problems here where i have to find individual forces.

problem 1: i can't find the normal force. how would i do it?

Code:
<img src=[PLAIN]http://img1.photobucket.com/albums/0903/badboyben03/p01.png>
[/PLAIN] [Broken]
i tried 2123.328N *(2825.008-701.68) and also tried 701.68N but neither of them worked.


problem 2: i can't find the tension force

Code:
<img src=[PLAIN]http://img1.photobucket.com/albums/0903/badboyben03/p03.png>
[/PLAIN] [Broken]
i tried 32.438N and 132.948 *(165.386-32.438) but also neither of them worked.

please help me. thanks.

Problem 1.
The normal force must produce the required centripetal acceleration.
This is also the case with problem 3.

Problem 1: Remember that in Newton's 2nd law, Fnet is a vector sum that reduces to (in this problem):
Fnet = Fnorm-Fgrav
Plug in your values appropriately to solve for the normal force on the pilot.

Problem 2: Same exact idea. You need to consider the directions of each force in order to add them together.
 

1. What is normal and tension force?

Normal force is the force exerted by a surface on an object that is in contact with it, perpendicular to the surface. Tension force is the force that is transmitted through a string, rope, or cable when it is pulled tight by forces acting on its ends.

2. How do you calculate normal and tension force?

The normal force can be calculated by multiplying the mass of an object by the acceleration due to gravity (9.8 m/s^2). Tension force can be calculated by using the equation F=ma, where F is the force, m is the mass, and a is the acceleration.

3. What are some real-life examples of normal and tension force?

Normal force can be seen when a book is resting on a table, or when a person is standing on the ground. Tension force can be observed when a person is pulling on a rope or when a bridge is being supported by cables.

4. How do normal and tension force affect an object's motion?

Normal force affects an object's motion by balancing out the force of gravity, keeping the object in equilibrium. Tension force affects an object's motion by providing a pulling force, causing the object to accelerate in the direction of the force.

5. Can normal and tension force be negative?

No, normal and tension force cannot be negative. They are both vector quantities, meaning they have both magnitude and direction. Negative values would indicate a force in the opposite direction, which is not possible for these types of forces.
