What are the two main functions of the hardware used in controlling a stepper motor? Using a schematic diagram, explain a microcontroller-based feedback control system for a stepper motor.
A stepper motor controller uses a 12 bit counter chip (a hardware counter). If one-step of the motor corresponds to a load movement of 0.2 mm, what is the maximum load movement (stroke) that could be controlled?
air confined in a tank has an initial temperature of 1700f and an initial pressure of 60 psia. if the air is cooled
two materials a and b of the same density are being considered for the design of a large plate that is 2 m wide and 3 m
A piston-cylinder assembly initially contains 4 mol of substance X in vapor phase at 0.8 bar and 373 K. The vapor is compressed isothermally and reversibly until the first droplet of liquid forms.
The mean and the standard deviation for N.
An inventor claims to have developed a power cycle operating between hot and cold reservoirs at 1175K and 295K, respectively, that provides a steady state power output of (a) 28 kw, (b) 31.2 kW, while receiving energy by heat transfer from the hot re..
If the concentration difference for diffusion across a thin film is doubled, what happens to the flux? If the diffusion coefficient across a thin film is doubled, what happens to the flux?
a fluid viscosity10-2 nsm2 density 800 kgm3 flows with a mean velocity of 4 cms in a 10 cm smooth pipe.a. what is the
A double-wall heat exchanger is used to transfer heat between liquids flowing through semicircular copper tubes. Each tube has a wall thickness of t = 3 mm and an inner radius of ri = 20 mm, and good contact is maintained at the plane surfaces by ..
Briefly describe the simplest heat treatment procedure that would be used in converting a 0.76 wt% C steel from one microstructure to the other
A hydraulic cylinder has a piston diameter of 2.2 inches, a fluid pressure of 1100 psi, a flow rate of 132 cubic inches per minute, and a stroke of 10.5 inches. Find the force and the velocity generated by the piston.
Determine the heat transfer rate from the steel plates of Problem 7.24 accounting for free convection from the plate surfaces. What is the corresponding rate of change of the plate temperature?
