Suppose the Ends of a 30-M Long Steel Beam Are $\degree$

Short Answer

Suppose the ends of a 30-m long steel beam are rigidly clamped at 0 $\degree$ C to prevent expansion. The beam has a cross-sectional area of 30 cm². What force against the clamps does the beam exert when it is heated to 40 $\degree$ C? ( $\alpha$ Steel = 1.1 *0-5/ $\degree$ C, Ysteel = 20 *1010 N/m²).
