A 1.8 degrees stepper motor is directly connected to a machine table driven by a lead screw with eight threads per inch. (Note that pitch is the axial distance traveled for one revolution of the screw).
Determine the axial distance traveled by the lead screw when an external input of 4355 pulses is sent to the motor. A separate encoder is connected to the other end of the lead screw. The encoder generates 180 pulses/rev. What will be the number of pulses in the above case? What will be an ideal response?
A machine used to shred cardboard boxes for composting has a first cost of $10,000, an AOC of $7000 per year, a 3-year life, and no appreciable salvage value. Assume you were told that the service provided by the machine will be needed for only 5 years, which entails a repurchase and retention for only 2 years. What salvage value, S, is required after 2 years in order to make the 2-year AW value the same as it is for its 3-year life cycle AW? Assume i = 10% per year. Solve using factors and, if assigned, using a spreadsheet and Goal Seek.
