Steel beams are used for load bearing supports in a building. Each beam is 4.0 m long with a cross-sectional area of 7.5 x 10 m and supports a load of 4.5 x 10 N. Young's modulus for steel is 210 x 10 N/m. (a) How much compression (in mm) does each beam undergo along its length?(b) Determine the maximum load (in N) one of these beams can support without any structural failure if the compressive strength of steel is 1.50 x 10 N/m.
