What has no fixed volume or shape?

What has no fixed volume or shape? A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape. The change from solid to liquid usually does not significantly change the volume of a substance. Which type of matter has […]

What are the 2 types of mantle?

What are the 2 types of mantle? Earth’s mantle is divided into two major rheological layers: the rigid lithosphere comprising the uppermost mantle, and the more viscous asthenosphere, separated by the lithosphere-asthenosphere boundary. What are the three types of mantle? The mantle is divided into several layers: the upper mantle, the transition zone, the lower […]

What are the methods of vibration analysis?

What are the methods of vibration analysis? Based on different types of vibrations, there are sensors designed to measure displacement, velocity and acceleration, with different measuring technologies, such as piezoelectric (PZT) sensors, microelectromechanical sensors (MEMS), proximity probes, laser Doppler vibrometer and many others. How vibration monitoring system works? An accelerometer is a sensor that produces […]

How do you find the zero state response?

How do you find the zero state response? To find the zero state solution, take the Laplace Transform of the input with initial conditions=0 and solve for Xzs(s). How do you find the impulse response of a system? Given the system equation, you can find the impulse response just by feeding x[n] = δ[n] into […]

What is input in the Universal Systems Model?

What is input in the Universal Systems Model? Inputs represent the basic materials or resources that will be transformed to the output. Feedback is the element of control. If the desired output is not achieved, the process and/or the inputs must be adjusted to achieve the desired result. What is the purpose of the Universal […]

Is open loop unstable?

Is open loop unstable? The open loop control system is marginally stable if any two poles of the open loop transfer function is present on the imaginary axis. Similarly, the closed loop control system is marginally stable if any two poles of the closed loop transfer function is present on the imaginary axis. What is […]

How does a stator work in a torque converter?

How does a stator work in a torque converter? The stator redirects oil from the turbine into the faster-rotating impellor blades to multiply torque. During deceleration, the direction of oil flow in the converter reverses because the turbine becomes the driving component. The stator must then freewheel to allow the oil to reverse its direction […]

How long should a conversation last?

How long should a conversation last? In the experiment, the average conversation lasted around 30 minutes. Kommers wrote he would have predicted this is longer than anyone would have wanted to talk. What questions do you need to have a conversation? Conversation Questions Getting to Know Each Other Do you have any pets? What was […]
