Bars AD and CE (E=105 GPa, a = 20.9×10-6 °C) support a rigid bar
ABC carrying a linearly increasing distributed load as shown. The
temperature of Bar CE was then raised by 40°C while the temperature of Bar
AD remained unchanged. If Bar AD has a cross-sectional area of 200 mm²
while CE has 150 mm², determine the following: the normal force in bar AD, the
normal force in bar CE, and the vertical displacement at Point A.

The SDOF system consists of a rigid beam that is massless. The rigid beam has a pinned (i.e., zero moment) connection to the wall (left end) and it supports a mass m on its right end. The rigid beam is supported by two springs. Both springs have the same stiffness k. The first spring is located at distance L/4 from the left support, where L is the length of the rigid beam. The second spring is located at distance L from the left support.arrow_forwardFor the system shown in Figure 2, u(t) and y(t) denote the absolute displacements of Building A and Building B, respectively.
