I understood every except, How do they get the 9 degrees in part c?

Yes.circuscircus said:So then is arctan(30/190) 9 degrees?
You don't need a radian calculator. (If ever you don't have a calculator handy, Google has one.)(I don't have access to a radian calculator right now), also how do they get the 19N?
Where did the 130 come from?circuscircus said:So the real F is sqrt(130^2+30^2) am I correct?
A force diagram, also known as a free body diagram, is a visual representation of the forces acting on an object. It shows the direction and magnitude of each force, including external forces and reaction forces, and helps to analyze the motion of the object.
To draw a force diagram, start by identifying the object and all the forces acting on it. Then, draw a dot or a box to represent the object and use arrows to represent the direction and magnitude of each force. Make sure to label each force and use a scale to indicate the relative size of each force.
The different types of forces on a force diagram include contact forces (such as friction and tension), action-at-a-distance forces (such as gravity and electromagnetic forces), and reaction forces (such as normal force and support force).
A force diagram can be used to solve a problem by providing a clear visual representation of all the forces acting on an object. By summing up all the forces in each direction, you can determine the net force and calculate the acceleration or motion of the object.
No, force diagrams are also used in other fields such as engineering and biomechanics. They are especially useful in analyzing the forces acting on complex systems, such as structures or human bodies, to better understand their motion and stability.
