Three forces of 300 N in the direction of N30E, 400N in the direction of N60E and
andreyandreev [35.5K]

Split up each force into horizontal and vertical components.

• 300 N at N30°E :

(300 N) (cos(30°) i + sin(30°) j)

• 400 N at N60°E :

(400 N) (cos(60°) i + sin(60°) j)

• 500 N at N80°E :

(500 N) (cos(80°) i + sin(80°) j)

The resultant force is the sum of these forces,

∑ F = (300 cos(30°) + 400 cos(60°) + 500 cos(80°)) i

… … …  + (300 sin(30°) + 400 sin(60°) + 500 sin(80°)) j N

∑ F ≈ (546.632 i + 988.814 j) N

so ∑ F has a magnitude of approximately 1129.85 N and points in the direction of approximately N61.0655°E.

Answer:

12.6 hp

Step-by-step explanation:

Represent the input by n.                              10.75 hp

Then 0.85n = 10.75 hp, and n (the input) is --------------- = 12.6 hp

                                                                           0.85

PSYCHO15rus [73]
This is an iteration method for finding the square root.

The ? is also your first initial guess.

? = 10.5

The iteration formula for the square root is actually.

√n =      (x + n/x)÷2.

Where x is your guess.
