Math Problem Statement

solve

A steel column has a 10 kip force acting on it at an angle of 35 degrees from horizontal. Calculate the X and Y components (Fx and Fy) of the force.

Solution

This problem involves breaking down a force vector into its horizontal (FxF_x) and vertical (FyF_y) components using trigonometric relationships. Given:

  • The magnitude of the force, F=10kipsF = 10 \, \text{kips} (which equals 10,000 lbs).
  • The angle of the force relative to the horizontal is θ=35\theta = 35^\circ.

Components of the force:

  1. Horizontal Component ( FxF_x ): Fx=Fcos(θ)F_x = F \cdot \cos(\theta)

  2. Vertical Component ( FyF_y ): Fy=Fsin(θ)F_y = F \cdot \sin(\theta)

Let's calculate these components now.The force components are:

  • Horizontal component (FxF_x): approximately 8191.52 lbs.
  • Vertical component (FyF_y): approximately 5735.76 lbs.

These represent the magnitudes of the components of the 10 kip force acting at a 35-degree angle from the horizontal.

Would you like further details or have any questions?

Here are 5 related questions to expand on this:

  1. How would the force components change if the angle increased?
  2. Can you calculate the resultant force if you were given both FxF_x and FyF_y but not the total force?
  3. What is the effect of the vertical force component on the steel column structure?
  4. How can this method of vector decomposition apply to forces in 3D?
  5. What happens to the horizontal and vertical components if the force is applied at a 90-degree angle?

Tip: When resolving forces into components, always ensure the angle is measured relative to the correct reference axis, usually the horizontal or vertical.
