1. A steel beam is placed vertically in the basement of a building to keep the floor above from sagging. The load on the beam is 5.80 10⁴ N, the length of the beam is2.52 m, and the cross-sectional area of the beam is 7.50 10³ m². Find the vertical compression of the beam. (Young's modulus of the beam is 200.0 10⁹ Pa.)

___________mm

2. A marble column with a cross-sectional area of 24.8 cm² supports a load of 7.0 10⁴ N. The marble has a Young's modulus of 60 GPa and a compressive strength of 200 MPa.

(You may enter your calculation using scientific notation (x.xxEy): for example: 3.24 x 105 may be entered as 3.24E5.)

What is the strain in the column?
