Consider a single-degree-of-freedom system with the following equation of motion. mä+ci+kx = 0 In free vibration, the response of the system is measured experimentally, as shown in the figure below. The equivalent spring constant is k = 5 N/m. Successive peak displacements are ₁ = 2 mm and 2 = 1 mm. If the period of oscillation of the system is Ta = 1 s, determine the mass of the system. ooooo 112.6158 kg 15.6411 kg 0.1251 kg 3.3785 kg 56.0576 kg X1 A Ta X2

We have a rectangular piece. We wish to manufacture a parallel slot along thepiece in a vertical milling machine and 50 cm from the edge. The width of the slot is 40 mm. TheDepth of the slot is 25 mm. For this, several rough cutting steps and aFine cut with a depth of 0.20 mm. The depth for each of the steps ofrough cut is limited to 1.75 mmAditional information:What is the number of blades used for the rough cutting steps?What is the number of blades used for the fine cutting step?

04 05 a Explain the reasons for the following: 1- The pure aluminum and the copper are generally rated as easy to machine 2- In ultrasonic machining, the stress produced by the impact of abrasive particles on the workpiece surface is high. 3- In rolling process, the coefficient of friction must be sufficient. 4- Difference in solidification between casting and welding processes. 5- Why is it desirable to use energy sources for welding that have high heat densities? 6- Why there might be a change in the density of a forged product as compared to that of the cast blank. D. A cylindrical workpart with D=2.5 in and h=2.5 in is upset forged in an open die to a height = 1.5 in. Coefficient of friction at the die -work interface = 0.10 The work material has a flow curve defined by: K= 40,000 lb/in' and n-0.15. Determine the instantaneous force in the operation (a) just as the yield point is reached (yield at strain = 0.002), (b) at height = 2.3 in. (c) h= 1.9 in, and (d) h = 1.5 in. a List…

I asked for problems 6 and 7 to be answered, but I did not get a properly structured answered as the example shows on problem number 1. Here is the link to the questions I already had answered, could you please rewrite the answer so its properly answered as the example shows (Problem 1)?   https://www.bartleby.com/questions-and-answers/it-vivch-print-reading-for-industry-228-class-date-name-review-activity-112-for-each-local-note-or-c/cadc3f7b-2c2f-4471-842b-5a84bf505857
