Acceleration = a = [P*cos(?) -µ*(M*g - P*sin(?) )]/M
Pulling a crate of mass M (in kg) with a rope by a force of P ( in Newtons) at an angle ? (? is in degrees) and a coefficient of friction µ gives an acceleration of magnitude a (in m/s2). The acceleration due to gravity is denoted by g. Use g = 9.8 m/s2.
Part A. Use Excel to creae vertical column of angles ranging from 10 degrees to 35 degrees in increments of 0.5 degrees. Convert these angles to radians in an adjacent column. 1 radian = 57.296 degrees.
Part B. Use Excel to create spreadsheet to determine the acceleration at each of the angles above for P = 650.0N , M= 160 kg, and µ=.39.
Part C. What is the maximum acceleration?
Part D. What is the angle (in degrees) that maximizes the acceleration?
the starting torque and line current if the motor is started with the stator starconnected. Assume that the stator and rotor copper losses are equal at standstill.
What is the data rate of a digital electrical communication system that uses 16 voltage levels to carry multiple bits with one voltage level, where each voltage level is kept at that level for a duration of 2 ms
Tell me everything you know about clippers, clampers, and diode clamps. Show me typical waveforms, clipping levels, clamping levels, and protection levels.
Develop with MATLAB, a fuzzy control system for controlling the power of a motor (0-350 rpm) based on the supported load (0-1700 lbs) thereby that at greater load develops more power. The system must contain at least 5 rules, but preferably 7.
Using the frequency sampling method, design a linear phase bandstop FIR filter with cutoff frequencies Ωc1 = π/3, Ωc2 = π/2, and Lh = 13. Realize the design as a frequency sampling filter.
Determine the junction capacitance per unit area.
Complete the following timing diagram (assume that X1 = 1, X2 = 0, X3 = 0, X5 = 1, and X4 is as shown). Flip-flops change state on falling edge of clock.
A half-wave rectifier circuit with a 1-k ohm load operates from a 120-V (rms) 60-Hz household supply through a 10-to-1 step-down transformer. It uses a silicon diode that can be modeled to have a 0.7-V drop for any current.
Design a multi-stage audio amplifier for delivering an average power of 400 mW to a 16 Ohm speaker from a microphone that produces a 10 mV peak sinusoidal signal and has a source resistance of 1 kW. Use standard NPN QN2222 for your design.
A 4- to 20-mA control signal is loaded by a 100 Ω resistor and must produce a 20- to 40-V motor drive signal. Find an equation relating the input current to the output voltage.
The Karnaugh map is a structured way to simplify a Boolean expression. Its main advantage is that it can always reduce an expression to its simplest SOP form. What does the final logic expression indicate?
An enhancement-type PMOS transistor has K'p W/L=100μA/V2 and Vt=-2V. If the gate is grounded and the source is connected to +5V, what is the highest that can be applied to the drain while the device operates in saturation
