Answer:
275 MPa, -175 MPa
-0.63636
450 MPa
Explanation:
= Maximum stress
= Minimum stress
= Mean stress = 50 MPa
= Stress amplitude = 225 MPa
Mean stress is given by
Stress amplitude is given by
Maximum stress level is 275 MPa
Minimum stress level is -175 MPa
Stress ratio is given by
The stress ratio is -0.63636
Stress range is given by
Magnitude of the stress range is 450 MPa
The answer would be C. 80%
Put 160 over 200 and find the GCF
160/200÷40=4/5=80%
You can’t accelerate while moving backwards. This is false because you can accelerate while moving backwards.
Answer:
no of revolutions = 56.62 rev
Explanation:
given data
rotates = 1560 rpm
travels distance = 18.5 meters
speed = 40.2 m/s
solution
first we convert here rev/min to rev/sec
rotates = 1560 rpm = 1560 × 0.0167 = 26.052 rev/sec
we get here no of revolutions that is
no of revolutions = spin rotate ÷ time ..........1
here time = distance ÷ speed
time = 18.5 ÷ 40.2
time = 0.4601 s
put value in equation 1 we get
no of revolutions =
no of revolutions = 56.62 rev
