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 * 10 ^{- 5}/ $\degree$ C,Y_steel = 20 *10¹⁰ N/m²).
