Circuit Problem and Description: Using the given components, design a pneumatic circuit which will operate a double acting cylinder (A) from any one of two identical valves. The double acting cylinder will move out when either push button (M1) or (M2) is pressed, or when they are pressed at the same time. When the buttons are released, the cylinder will return to the initial position. Materials: Part # Component Description Quantity SAI 2026 Double acting cylinder SAI 2015 Normally closed 3/2 way valves operated by push button SAI 2023 Pneumatically piloted 5/2 way monostable valve SAI 2007 2 1 "OR" logic function valve 1 Teske Circuit Problem and Description: Using the given components, design a pneumatic circuit which will correctly and safely operate this machine control application. WWith this circuit, it must be possible to regulate the delay of a double acting cylinder (A). The cylinder will be driven by a valve, actuated by two pneumatic push buttons. One of the two push buttons…

QUESTION 14 Which one of the below statements is true? For a grounded link rotating with constant angular speed, the magnitude of the velocity vector of a point increases as the point moves away from the pivot. Ob. Kutzbach formula (or criteriong is always reliable in predicting the actual degrees of freedom for any mechanism. C. Springs are considered as links for degree of freedom calculations. O d. Satistying the Grashof criterion means that none of the links in a mechanism makes full rotations.

please answer and explain be specific and i will upvote if correct and explained

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.

QUESTION 2 ' а) Besides temperature measurement that is based on thermal expansion, there are also thermal sensors that are based on other factors. i. Describe on how the RTD and thermistor measure the temperature and difference between them. ii. Given the temperature for RTD in Figure 1 is 155°C, coefficient of resistance for RTD, a is 0.0035°C'' and resistance for the RTD is 352 at 0°C. The bridge is operated in a balanced condition. Find the value of R1, if R2= R3. R3 R2 G RTD RRTD Ri E, Figure 1 Wheatstone Bridge
