1. Suppose the ends of a 20-m-long steel beam are rigidly clamped at 0C to prevent expansion. The rail has a cross-sectional area of 30 cm2. What force does the beam exert when it is heated to 40C? (steel = 1.1 105/C, Ysteel = 2.0 1011 N/m2).

Here is the answer for the question – 1. Suppose the ends of a 20-m-long steel beam are rigidly clamped at 0C to prevent expansion. The rail has a cross-sectional area of 30 cm2. What force does the beam exert when it is heated to 40C? (steel = 1.1 105/C, Ysteel = 2.0 1011 N/m2).. You’ll find the correct answer below

The Correct Answer is

2.6 105 N

Reason Explained

2.6 105 N is correct for 1. Suppose the ends of a 20-m-long steel beam are rigidly clamped at 0C to prevent expansion. The rail has a cross-sectional area of 30 cm2. What force does the beam exert when it is heated to 40C? (steel = 1.1 105/C, Ysteel = 2.0 1011 N/m2).
