OpAmps are key active building blocks in elec- trical circuits, and are commonly used in many applications such as amplifying sensor signals, or implementing various lters and compensators in electronic controllers. Due to very high open-loop gain, OpAmps are typically used with negative feedback, and with proper characteristics, the closed- loop gain of the ampli er can be controlled primarily by the

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
