Document Summary
Answer the word questions on the test pages. Incremental encoders are usually more expensive than absolute encoders since they require more wires and optical sensors to operate. When used as a tachometer, a dc motor will produce a voltage that is proportional to angular velocity. Adding a larger resistance across the leads of a dynamometer"s generator increases the load on the motor. Piezoelectric accelerometers work by converting the force applied to a known mass into a resistance change measured by a wheatstone bridge. Adding the accelerometer to the tip of the cantilever beam (lab #7) increased the natural frequency, , of the system by a small amount. Based on this equation, what are two of the. Part 2: closed book, closed notes, one 8. 5x11 inch hand-written formula sheet allowed: [4] describe and/or sketch 2 methods for measuring the linear velocity of a piston in a small briggs & stratton engine.
