Answer: hello the image related to your question is missing attached below is the missing image
answer :
1.47°
Explanation:
First we have to determine the displacement
first : apply law of similar triangles
Scd / 1 = Sef / 3
Fcd ( displacement ) = 3Fef - 80
= 3(30) - 80 = 10 kip
angle of tilt ( θ ) = cos^-1 ( 1 / 10 )
= cos^-1 ( 0.1 ) = 1.47°
attached below is the detailed solution on the displacement value
Answer:
<u>The blade undergoes 40 revolutions, so neither of the given options is correct! </u>
Explanation:
The revolutions can be found using the following equation:
Where:
α is the angular acceleration
t is the time = 2.5 s
is the initial angular velocity = 1500 rev/min
First, we need to find the angular acceleration:
Now, the revolutions that the blade undergo are:
<u>Therefore, the blade undergoes 40 revolutions, so neither of the given options is correct! </u>
I hope it helps you!
