Question
iven: P = 35 kN; θ = 15°; α = 75°What is the a-component (kN) of P.QUESTION 3ANSWERA.9.38B.31.38C.20.59D.10.59
Solution
The question seems to be asking for the a-component of a force vector P. This can be calculated using the formula:
P_a = P * cos(α)
Given that P = 35 kN and α = 75°, we can substitute these values into the formula:
P_a = 35 * cos(75°)
Before calculating, ensure that your calculator is set to degrees, not radians. The cosine of 75 degrees is approximately 0.2588190451.
So, P_a = 35 * 0.2588190451 ≈ 9.06 kN
Therefore, the closest answer would be A. 9.38 kN. However, please note that the exact answer may vary slightly depending on the precision of the cosine value used.
