Math Problem Statement

If Force CA was determined to be equal to 436.4 N, it's horizontal component CAx = _______N. Answer has 2 decimal places, no unit. (2 Points)

If Force CA was determined to be equal to 436.4 N, it's horizontal component CAx = _______N. Answer has 2 decimal places, no unit.

Solution

To find the horizontal component CAxCA_x of the force CACA, we use trigonometry. From the diagram, it looks like the force CACA has a direction along a 3-4-5 triangle, indicating that the angle between CACA and the horizontal axis is determined by the ratio of the opposite and adjacent sides (i.e., 3 and 4).

The horizontal component CAxCA_x can be calculated as follows:

CAx=CA×45CA_x = CA \times \frac{4}{5}

Given that CA=436.4NCA = 436.4 \, \text{N}, we substitute:

CAx=436.4×45=436.4×0.8CA_x = 436.4 \times \frac{4}{5} = 436.4 \times 0.8

Now, let's calculate that.The horizontal component CAxCA_x is 349.12N349.12 \, \text{N}.

Do you have any further questions or would you like more details? Here are some related questions to deepen your understanding:

  1. How would you calculate the vertical component of CACA?
  2. What is the significance of using a 3-4-5 triangle in this problem?
  3. How do angles affect the calculation of force components?
  4. What method would you use to find the magnitude of the resultant force if both components are known?
  5. Can this same approach be applied to force CBCB, and what would be different?

Tip: Always ensure that the force vector components add up correctly using vector addition when resolving forces.
