During heavy lifting a disc between spinal vertebrae is subjected to a $5200$ N compression force what pressure is created on the disc Pacal assuming that the disc has the uniform circular cross$-$section $1\mathrm{.}95$ cm and radius what formation is produced in centimeters if the disc is $\mathrm{.}65$ cm thick and has a young modulus of $1\mathrm{.}25\backslash$times $10$ to the ninth Newton over meter squared
