What are the three elementary parts of a vibrating system?
1 answer:
Answer:
the three part are mass, spring, damping
Explanation:
vibrating system consist of three elementary system namely
1) Mass - it is a rigid body due to which system experience vibration and kinetic energy due to vibration is directly proportional to velocity of the body.
2) Spring - the part that has elasticity and help to hold mass
3) Damping - this part considered to have zero mass and zero elasticity.

Answer:
16 seconds
Explanation:
Given:
C = 60
L = 4 seconds each = 4*4 =16
In this problem, the first 3 timing stages are given as:
200, 187, and 210 veh/h.
We are to find the estimated effective green time of the fourth timing stage. The formula for the estimated effective green time is:
Let's first find the fourth stage critical lane group ratio , using the formula:
Solving for , we have:
Let's also calculate the volume capacity ratio X,
X = 0.704
For the the estimated effective green time of the fourth timing stage, we have:
Substituting figures in the equation, we now have:
15.78 ≈ 16 seconds
The estimated effective green time of the fourth timing stage is 16 seconds

Explanation:
Electrical current can be measured according to the rate of electric charge flow in any electrical circuit:
the derivative of the electric charge by time determines the momentary current.
i(t) will be the momentary current I at time t in amps (A).
Q(t) will also be the momentary electric charge in coulombs (C).
t is the time in seconds (s).
so if the current is constant:
I = ΔQ / Δt
I will be the current in amps (A).
ΔQ will be the electric charge in coulombs (C), which is expected to flows at time duration of Δt.
Δt is the time duration in seconds (s).
