Answer:
a)f=2.25 Hz
b)Time period T=.144 s
c)tex]V_{max}[/tex]=0.42 m/s
d)Phase angle Ф=87.3°
e)
Explanation:
a)
Natural frequency
=14.14 rad/s
w=2πf
⇒f=2.25 Hz
b) Time period
T=
Time period T=.144 s
c)Displacement equation
Boundary condition
t=o,x=0.03 m
t=0,v=.02m/s , V=
Now by using these above conditions
A=0.03,B=0.0014
x=0.03 cos14.14 t+0.0014 sin14.14 t
⇒x=0.03003sin(14.14t+87.3)
=0.42 m/s
d)
Phase angle Ф=87.3°
e)
Maximum acceleration
=6.0041
Answer:
Mechanic: a person who <u>repairs and maintains machinery</u>
Mechanical engineers: design <u>power-producing machines</u>
Explanation:
Answer:
Spheroidite < Pearlite < Bainite < Martensite
Explanation:
Given materials in the question :
Pearlite, martensite, bainite and spheroidite
Now,
the correct order of the increasing toughness out of the given materials is
Spheroidite < Pearlite < Bainite < Martensite
These all are the forms of steel formed by different heating and cooling processes.
So what happens is the host will not kill the y no se que hacer para no one can see it in
