Esfuerzo Normal Promedio || Ej. 1 || Problemas 1.1 y 1.2 Beer & Jonhston 8 ed

Problem Statement: 1.1 Two solid cylindrical rods AB and BC are welded together at B and loaded as shown. Knowing that d1 = 30 mm and d2 = 50 mm, determine the average normal stress at the midsection of (a) rod AB, (b) rod BC. 1.2 Two solid cylindrical rods AB and BC are welded together at B and loaded as shown. Knowing that the average normal stress must not exceed 150 MPa in each rod, determine the minimum allowable values ​​of the diameters d1 and d2. 1.1 Two solid cylindrical rods AB and BC are welded together at B and loaded as shown.
