Answer:
3
Explanation:
From the question given above, the following data were obtained:
Length (L) = 3 m
Height (H) = 1 m
Mechanical advantage (MA) =.?
The ideal mechanical advantage for the system can be obtained as follow:
MA = L/H
MA = 3/1
MA = 3
Therefore, the ideal mechanical advantage for the system is 3
Answer:
a) KE = 888.26J
b) N = 294.5 turns
Explanation:
For the kinetic energy:
The inertia is:
So, the kinetic energy will be:
Now, friction force is:
Ff = μ*N = 0.80*5N = 4N
The energy balance would be:
Kf - Ko = Wf where Kf=0; Ko = 888.26J; and Wf is the work done by friction force.
Wf = -Ff*d = -Ff*N*2*π*R where N is the amount of turns it gives.
Replacing these values into the energy balance:
0-888.26=-4*N*2*π*0.12
-888.26=-0.96*π*N
N=294.5 turns
I would say the number of harmonics decrease, because you're adding to the frequency of a wave.
I hope this helps :)
Answer:
Below in bold.
Explanation:
Newton's Second Law:
Force = mass * acceleration
So
Force = 24.5 * 2.3
= 56.35 Newtons.
