Suppose the Ends of a 30-M-Long Steel Beam Are Rigidly

Short Answer

Suppose the ends of a 30-m-long steel beam are rigidly clamped at 0°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°C? (αSteel = 1.1 × 10⁻⁵/°C, Ysteel = 20 × 10¹⁰N/m²).
