- 4-You are making a bookshelf (shown below) to carry books that range from 8½" to 11" in height and would take up 29" of space along the length. The material is wood having a Young's Modulus of 3.66 ksi, thickness of 3/8", and width of 12". You want to find the maximum vertical deflection of the bookshelf. The vertical deflection of the shelf is given by: -0.67665 x10 8x4 -0.26689x105 x3 +0.12748x10³ x² -0.018057=0 x Bookshelf Booksarrow_forwardThe difference in water surface levels in two tanks, which are connected by three pipes in series of lengths 300 m, 170 m, and 210 m, having diameters 300 mm, 200 mm, and 400 mm, respectively, is 12 m. Determine the rate of flow of water if coefficients of friction are 0.005, 0.0052, and 0.0048, respectively.

- The single degree of freedom (SDOF) system that you studied under free vibration in Assignment #3 - Laboratory Component has been subjected to a strong ground motion. The acceleration at the base (excitation) and the acceleration at the roof (response) of the SDOF system was recorded with sampling rate 50 Hz (50 samples per second, or dt= 0.02 seconds). The file ElCentro.txt includes the two columns of acceleration data. The first column lists the acceleration at the base of the SDOF system. The second column lists the acceleration at the roof of the SDOF system. (a) Plot the time histories of the recorded accelerations at the base and at the roof of the SDOF system. (b) Compute the acceleration, velocity and displacement time histories of the roof of the SDOF system subjected to the recorded base acceleration using the Central Difference method. Plot the accel- eration, velocity and displacement time histories. Plot the restoring force, the damping force, and the inertia force time…arrow_forwardUsing the method of virtual work, for the truss shown below, determine the horizontal displacement of joint A.
