A circle of diameter d =25 cm is scribed onto an unstressed square of 40cm*40cm aluminum plate if thickness t= 2cm. Force are applied to the plate such that the stresses in the x and y directions are 85MPa ahd 140MPa. If aluminum has a Young's modulus E=70 GPa and a poisson ratio v = 0.33, determine.

1) The change in the length of the circle diameter AB.
2) the change in the length of the circle diameter CD.
3)The change in the thickness of the plate
4) The change in the volume of the plate

For me a person with a phd and who knows what there talking about.i know the chances of a radiation leak is low but if it does the area within a 96.3 mile radius would be unusable because of contamination

107.1 mhz has higher energy photons. the photon energy increases directly proportional to frequency. however if the station operating on 90.5 mhz transmitter's power is 1.184 times or higher than that of the station operating on 107.1 mhz transmitter's power, then the 90.5 mhz signal will have higher energy because the additional photons makeup the difference. the total energy in electromagnetic radiation is the product of the energy per photon and the number of photons (i.e. amplitude of the wave) in the radiation.
