I=.5*m*r^2 =.5*5.8*.6^2 =1.044

Homework Statement A rotating uniform-density disk of radius 0.6 m is mounted in the vertical plane. The axle is held up by supports that are not shown, and the disk is free to rotate on the nearly frictionless axle. The disk has mass 5.8 kg. A lump of clay with mass 0.5 kg falls and sticks to...

would -264308724.8 be correct or should it be positive

ok i redid my calculations again and got -264308724.8 N/m^2

i converted it to meters because everything we do is always in meters

N/m^2

no its in meters because its supposed to be in meters. i got 12021839.34 N/m and it was wrong

it didn't work with those numbers idk what to do anymore but thank you

So i redid it and got Ao= .01539 and the force should be -950.6

To find Ao i converted cm to m and then divided it by 2 to get the radius then used the area of a circle formula and the force would be gravity

Ao= 0.9079 I know force= m*a and I know that m is 97 but i don't know a

nevermind it said that was wrong no matter which way I tried :(

okay so i know that Lo= 2.9m and delta_L= 0.0149m but I'm not sure how to get F and Ao

young's modulus is stress/ strain which is (F*Lo)/(Ao*delta_L) I do not know how to get the numbers and I don't understand how they relate to interatomic stiffness
