Answer:
the maximum deformation undergone by the spring = 47.46 cm
Explanation:
Using conservation of momentum:
where:
Then;
v = 19.375 m/s
However ; using conservation of energy to determine the maximum deformation undergone by the spring ; we have:
x = 0.4746 m
x = 47.46 cm
Thus, the maximum deformation undergone by the spring = 47.46 cm
Answer:
Angular velocity of the disk is 8.552 rad/s
Explanation:
It is given that,
Rotational kinetic energy, KE = 1280 J
The moment of inertia of the disk, I = 35 kg m²
We have to find the angular velocity of the disk. In rotational mechanics the kinetic energy of the disk is given by :
Hence, the angular velocity of the disk is 8.552 rad/s.
Answer:
the efficiency of hydralic is 79.88%
Explanation:
convert mm to m
1mm = (1/1000)m
diameter of pipe upsteam
d₁= 90mm= 0.09m
diameter of pipe downsteam
d₂= 30mm = 0.03m
finding velocity of upsteam
recall Q=A₁V₁
V₁=Q/A₁
V₁=3.14m/s
velocity of downsteam
V₂= Q/A₂
V₂= 28.29m/s
mass flow rate
m= ρQ
ρ is the density of water
m = 1000× 0.02
m= 20kg/s
the efficiency of hydralic is 79.88%
