Two stepping motors are used in an open-loop system to drive the leads crews for .r-y positioning. The range of each axis is 250 mm. The shafts of the motors are connected directly to the tea screws, the pitch of each lead screw is 3.0 mm, and the number of step angles on the, tipping moot IS 125.
(a) How closely can the position of the table be controlled, assuring there are no mechanical errors in the positioning system?
(b) What are the required pulse train frequencies and corresponding rotational speeds of each stepping motor to drive the table at 275 mm/min in a straight Line from point (x = 0,y = 0) to point (x = 130mm, y = 220mm)?
Review recent magazine and newspaper articles concerning nuclear power. Prepare a report that explores the advantages and disadvantages of developing additional nuclear power facilities.
A voltage source v(t)=t*sin(t) is connected to a capacitor with C= 2 farad. Find the energy stored in the capacitor from t=0 to t=1 second.
Audio data is stored in digital form on a DVD or CD and this data is converted back toanalog form by passing the digital data to a Digital to Analog(D/A) converter. What is the number of bits of resolution that is typically used in consumer audio ..
Determine the strength of a uniform electric field if it is to have the same energy as that established by a magnetic field of flux density 0.8 T. Assume that the relative permeability of the magnetic field and the relative permittivity of the ele..
Draw a state diagram for an FSM that has an input X and an output Y. Whenever X changes from 0 to 1, Y should become 1 for two clock cycles and then return to 0, even if X is still 1. Develop both the Moore and Mealy machines.
A chemical plant needs a microprocessor-driven alarm system to warnof critical conditions in one of its chemical tanks. Thethank has four HIGH/LOW (1/0) switches that monitor temperature(T), pressure (P), fluid (F), and weight (W).
determine the voltage drop across the 20 Ohm resistor with respect to the 48 V source. I'm having difficulty understanding why the voltage comes out to a negative 12 V, then to a negative 8 V.
A jogger accelerates from rest to 3.75 m/s in 3.58 s. A car accelerates from 16.7 to 31.6 m/s also in 3.58 s. (a) Find the magnitude of the acceleration of the jogger. (b) Determine the magnitude of the acceleration of the car.
