A 62-N force acts at 30 degrees and a second 62-N force acts at 60 degrees. Determine the resultant force. What is the magnitude and direction of the force that produces equilibrium?

Final answer:

To determine the resultant force, you can decompose the given forces into their x and y components and then add the components separately. The magnitude of the resultant force can be found using the Pythagorean theorem, and the direction can be found using trigonometry.

Step-by-step explanation:

In order to determine the resultant force, we will use the concept of vector addition. We can decompose the given forces into their x and y components. The first force of 62 N at 30 degrees can be written as 62*cos(30)i + 62*sin(30)j, and the second force of 62 N at 60 degrees can be written as 62*cos(60)i + 62*sin(60)j. Adding the x and y components separately, we get 62*cos(30) + 62*cos(60) and 62*sin(30) + 62*sin(60), respectively. By calculating these values, we find that the resultant force is approximately 0.866i + 89.9j N.

To find the magnitude of the resultant force, we can use the Pythagorean theorem: |R| = sqrt((0.866)^2 + (89.9)^2) ≈ 89.9 N.

The direction of the resultant force can be found using trigonometry: tan(theta) = (62*sin(30) + 62*sin(60)) / (62*cos(30) + 62*cos(60)). By calculating this expression, we find that theta ≈ 89 degrees.

Given:

62 N force acts at 30 degrees
62 N force acts at 60 degrees

To determine the resultant force, we can use the CMPLX function of the calculator and input:

62∠30 + 62∠60

Ans:

119.77∠45. Therefore, the resultant force has a magnitude of 119.77 N force and at an angle of 45 degrees.
