Answer:
Wy = - 268.3*cos(42) = - 199.38 [N]
Wx = 268.3*sin(42) = 179.52 [N]
Explanation:
To solve this problem we must make a free body diagram, in the attached image we can see a free body diagram.
Taking the inclined X & y axes with the same angle of 42°, we can see that the weight can be decomposed on both axes.
Since the angle is adjacent to the y-axis, we can use the cosine function
Wy = - 268.3*cos(42) = - 199.38 [N]
Wx = 268.3*sin(42) = 179.52 [N]
Answer:
Explanation:
Given
Weight of helicopter
inclination of blades with vertical
Suppose is the lifting Force
Now using F-B-D
as helicopter is moving with constant velocity
balancing forces in Vertical Force
Now sin component of lift is air resistance
where R=air resistance
