A vertical steel beam in a building supports a load of 7 x 104 N. If the length of the beam is 4 m and its cross--sectional area is 8 x 10-3 m2, find the distance that the beam is compressed along its length.
Young's modulus for steel is
3.75 x 10-2 m |
||
2.25 x 10-5 m |
||
1.75 x 10-4 m |
||
1.75 x 10+2 m |
