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.

- Draw the updated network. Calculate the new project completion date. Check if there are changes to the completion date and/or to the critical path. Mention the causes for such changes, if any. New network based on the new information received after 15 days (Correct calculations, professionally done). Mention if critical path changes or extended. Write causes for change in critical path or extension in the critical path.arrow_forwardThe single degree of freedom system shown in Figure 3 is at its undeformed position. 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. The two buildings are connected using a linear viscous damper with damping coefficient c. Due to construction activity, the floor mass of Building B was estimated that vibrates with harmonic displacement that is described by the following function: y(t) = yocos(2πft). Figure 2: Single-degree-of-freedom system in Problem 2. Please compute the following related to Building A: (a) Derive the equation of motion of the mass m. (20 points) (b) Find the expression of the amplitude of the steady-state displacement of the mass m. (10 pointsarrow_forward
