- INSTRUCTION: This is a topic for Pneumatic Controls Engineering. You may use Fluidsim to illustrate the solution (circuit diagram) to the given problem. Please refer to the problem below and apply the appropriate pneumatic system circuit. PROBLEM: The prototype of a pneumatic domestic rubbish compactor (under table model) is operated with a maximum working pressure of p = 3bar = 300 kPa. It is equipped with a pre-compactor (1A) including glass crusher as well as a main compactor (2A), which exerts a maximum force of F = 2200 N. When a start button is pressed, first the pre-compactor advances, then followed by the main compactor. The subsequent return stroke of both double-acting cylinders takes place simultaneously. In the event that the main compactor does not reach the forward end position — rubbish bins full —, the return stroke of both cylinders is initiated by a pressure sequence valve. It is set to switch at p = 2.8 bar = 280 kPa.Three springs are connected to a mass and to fixed supports. When the coordinate y is equal to zero, there is no spring force. Your tasks: Tw m k3 Fload Ő nly A Draw the free body diagram for the mass m including all 3 spring forces and the load force Fload). ( Figure 1: System schematic for Problem 1. B Draw the free body diagram for the mass m, but combine the springs into one equivalent spring with spring constant keq. Write the equivalent stiffness of the spring keq in terms of the other spring constants. (3 C Given that k₁ = 300 N/m, k₂ = 100 N/mnd k3 = 200 N/mand Fload = 300 N, calculate the loaded deflection Yloaded D Compute the amount of potential energy stored in each spring. E Compute the forces, in Newtons, in each spring and denote them as F₁, F2, and F3 when the load from Part D is applied. WhThe shaft pulley system has a universal joint at point 0. So it is supported by a slide at point A bearing and fixed support at point C. There is a mass of 12kg on the pulley and subject to the belt tensions but the mass of the shaft is negligible. a) draw the FBD of the assembly b) write the static equilibrium equations for the assembly c) explore the assembly and come up with the possible FBD for each component d) write the static equilibrium equations for the each component FBD.

Assume that the rod is massless, perfectly rigid, and pivoted at point P. When the rod is perfectly horizontal, the angle 0 = 0, the displacement y 0, and the springs are in neither tension nor compression. Gravity acts on the system (e.g. on mass M). We assume that y is a small displacement. A mass M is attached at the end of the rod.

Figure C1.2 shows a mechanism that is typical in the tank of a water closet. Note that flapper C is hollow and filled with trapped air. Carefully examine the configuration of the components in the mechanism. Then answer the following leading questions to gain insight into the operation of the mechanism. 1. As the handle A is rotated counterclockwise, what is the motion of flapper C? 2. When flapper C is raised, what effect is seen? 3. When flapper C is lifted, it tends to remain in an upward position for a period of time. What causes this tendency to keep the flapper lifted? 4. When will this tendency (to keep flapper C lifted) cease Plz connect me if you want to explan subject for me .... +962 79180149 Thx
- which equation is used if the system underdamped. can you pls share the whole eqnIn this system, there are two mass elements: m₁ and m₂. They are con- nected by a spring. m₁ is also connected to a massless rod, which can rotate at its midpoint. The other end of this massless rod is connected to another massless rod, which is connected to the ground through a spring and a damper. This configuration forms the basis of the system. You may assume small deflections for this problem and that the vertical connections are rigid links. When the coordinates y₁, y2, y are equal to zero, the gravi- tational force on the masses is covered by springs (the system is at its static deflection). Two input forces, fi and f2, are applied on the masses m₁ and m2 respectively. HINT: You should not consider the gravity force in your solution. Your tasks: A Short Answer: Which elements (refer to them by their corresponding constants) can store or possess energy in this system? B Draw the FBD for each mass (one for each of m₁ and m₂.

N ?Problem 1: You have been hired to design a family-friendly see-saw. Your design will feature a uniform board (mass M=10 kg, length L = 3.7 m) that can be moved so that the pivot is a distance d from the center of the board. This will allow riders to achieve static equilibrium even if they are of different mass, as most people are. You have decided that each rider will be positioned so that his/her center of mass will be a distance xoffset ;= 17 cm from the end of the board when seated as shown. You have selected a child of mass m = 29 kg (shown on the right), and an adult of mass m2 = 62 kg (shown on the left) to test out your prototype.
