In Problem 5.48, let a = 2.5 m. Determine the rotation at the section where M0is applied.

Problem 5.48

The beam in Figure P5.48 is made of an aluminum alloy (E = 72 GPa) and has a rectangular cross section with external dimensions 80 mm by 100 mm and a wall thickness of 10 mm. The identical springs have constant k = 300 kN/m. A couple M0is applied at distance a from the left end. Let M0 = 15 kN • m and a = 1.50 m. Determine the rotation of the section where M0 is applied.
