Question: 134 segments ab and bcd of beam abcd are pin...

Question details

1.3-4 Segments AB and BCD of beam ABCD are pin connected at x -4 m. The beam is supported by a sliding support at A and roller supports at C and D (see figure). A triangularly distributed load with peak intensity of 80 N/m acts on BC. A concentrated moment is applied at joint D (a) Find reactions at supports A, C, and D (b) Find internal stress resultants N, V, and M at x-5m. (c) Repeat parts (a) and (b) for the case of the roller support at C replaced by a linear spring of stiff- ness k200 kN/m (see figure) 80 N/m 200 N.m at joint D --_ 4 m B4m 3 m Part (c)- Pin connection PROBLEM 1.3-4
