999. Feb 23, 2010. #6. There is something wrong with your arithmetic. 1) PE between start and point of impact = 6x9.81x55 = 3237j 2) KE at point of impact = 6*30*30/2 = 2700j 3) Energy lost during fall = 3237-2700 = 537j 4) Lost to heat due to wind resistance Edit: This can be verified by doing the calculations for a 55m drop in a vacuum which ...
HI, If you have a resistor, say 10 Ohms, and you apply a voltage across it, say 10V. the resistor will dissipate V*R=10W. So you would need a 10W resistor for the job. If you would have tracked your units, you would have seen that. V*R = 10 V * 10 Ω= 100 V⋅Ω. Since V⋅Ω is not a unit of power, you would have seen that your equation was ...
Voltage is E = U/q where U is potential energy and q is charge in coulombs. Knowing this, apparently the potential energy between the two ends of a 1.5V battery can be found like so: 1.5V = U/1.602x10^-19 = 2.4x10^-19J So hold on a sec, does that mean that the battery has a potential energy of 2.4x10^-19?
Applying a pulse to a solenoid is not repetitive trough a series capacitor fed by DC. The formula you are looking for is C=Q/V ---->Capacitance = Charge/Voltage And Q=It ---->Charge = Intensity x time Replacing the second Q into the first formula, you obtain C=It/V So the time needed to kick your coil is t = VC/I ----->time = Voltage x capacitance / intensity but Voltage / Intensity ...
Details: Understand bidirectional power flow control, use inverters or converters for bidirectional energy transfer. Mechanical System Design: Reference: "Mechanical Engineering Design" by Joseph E. Shigley and Charles R. Mischke. Details: Focus on mechanical aspects, including lifting mechanisms, safety features, and braking systems.
divinesage. Joined Sep 13, 2010. 7. Nov 5, 2010. #1. A 10 hp, 200V DC shunt motor has an armature resistance of 1 ohm and shunt field resistance of 100 ohms. At no-load, the motor draws 3A from the 200V supply and and runs at 1500 r/min. Calculate the rotational losses under this operating condition. Ans: 199W.
An inductor is rather like the mechanical inertia of a mass, which stores energy equal to 1/2 mv² where m is its mass and v is its velocity. An inductor stores energy equal to 1/2 LI², where L is the inductance and I is the current through the inductor.
Jul 28, 2019. #2. Hi Bob, Run the sim. place the cursor on the component you wish to measure the power, press down hold the ALT key, the cursor should change to a thermometer. Left click mouse, the power will be plotted. OK. E.
For stepper motor or split phase induction motor: R_L=X_L (if R_L<X_L, then connect additional resistor in series with C); X_C=2*X_L (if C connected in series with L); X_C=X_L (if C connected in parallel to L). REACTANCE CALCULATOR. MaxHeadRoom said: Still does not look right, compared to the SloSyn example motors.
There is an electrical resonance frequency and one or more mechanical resonance frequencies. These show up as peaks in efficiency. Your lowest efficiency peak is mechanical. If the enclosure is tuned to the mechanical peak of the speaker, all the bass notes will seem to resemble the mechanical resonant frequency of the speaker.
