(1) A vertical steel beam supports a load of 7.0 imes 10^(4)N. If the unstressed length of the beam is 4.0m, and its cross-sectional area is 8.0 imes 10^(-3)m^(2), find the amount of compression that the beam undergoes.
(1) A vertical steel beam supports a load of 7.0 x 104 N. If the unstressed length of the beam is 4.0 m, and its cross-sectional area is 8.0 x 10-3 m2, find the amount of compression that the beam undergoes.
