a cylindrical metal strut that forms part of a landing gear of a jet aircraft has a diameter of 24mm and is 0.35m long.during landing the maximum compressive force reaches a value of 50kn
Assuming that the elastic limit of the strut is not exceeded calculate the reduction in length of the strut under this compressive force
the young modulus for the metal is 80GNm-2
please help i found that the area is : 4.52 x 10^-4 m2
