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
A pendulum is probably the most common showing of this example. As the pendulum swings down, it converts its potential energy (height) into kinetic energy (velocity). At the lowest point the kinetic energy is the highest and the potential is the lowest. At the highest point in its swing the velocity is zero so the kinetic energy is zero and the potential energy is at a maximum (greatest height).
Three of the statements are true. 'D' is false.
Glass and rubber are excellent insulators, total duds as conductors.
I’m not sure I think if you google it it should pop up or go on quizlet sorry
Gamma rays because it has more penetrating power and frequency but shorter wavelength.
