What are the uses of double pulley in physics?
The amount of force required to lift a weight is inversely proportional to the number of suspension lines. A multiple pulley system allows the load to be distributed across several lines and greatly reduces the amount of force required to lift the weight.. The load that takes mechanical power to lift with a single pulley can be lifted by a single person with a multiple pulley set-up
What is the input and output of a load cell?
The input of a load cell is the force or weight applied to it. The output of a load cell is an electrical signal, typically in the form of voltage or current, that is proportional to the applied force or weight.
What is the relationship between extension and mass?
Within a materials elastic limit, the extension of a uniform section (like a wire) will be proportional to the tensile load. The graph of load (mass) v extension will be a straight line
How does deflection of a beam vary with moment of inertia?
Deflection is inversely proportional to moment of inertia, the larger the moment of inertia the smaller the deflection. Deflection is (with a simple centerloaded beam) is PL^3/48EI The various deflections are as follows: (i) for a simply supported beam with point load (center)=PL^3/48EI (ii) // // // UDL= 5PL^4/384EI (iii) for a cantilever with point load= PL^3/3EI (iv) // // with UDL= PL^4/8EI visit deflection calculator http://civilengineer.webinfolist.com/str/sdcalc.htm
What will be the effect of displaced water if load is added into ship float in ocean?
More water will be displaced equal to the load placed on the ship as long as the ship continues to float. This is not equal in volume, but equal in mass to that of the load.
Why dc series motor is never started on light load?
the speed N is inversely proportional to armature current I. At light loads this current is very small. Hence motor will run at very high speed when started on no load/light load.........
Why the series motor is started with some minimum load?
In series motor, At no Load Condition the flow of Armature Current is low, then the Flux is also low. Flux is inversely proportional to speed. If flux is decrease the speed is rapidly increase it spoil the rotor parts...... so SERIES MOTOR is start with LOAD.....
Why is circuit current reduced when a capacitors added to the circuit?
In the case of an a.c. circuit, capacitors oppose current because of their capactive reactance, expressed in ohms. Capacitive reactance is inversely-proportional to the capacitance of the capactor and to the frequency of the supply. So, adding a capacitor is series with an existing load will reduce the load current. On the other hand, adding a capacitor in parallel with an existing load will decrease the load current.
What happens to the current flow in a circuit when a second component is added in series?
The total current decreases.According to the Ohm's law the current & the resistance are inversely proportional so when we put a load in series with the existing load, the resistance of the circuit increases therefor the current decreases.
What is the effect of load resistance on ripple voltage in presence of filter capacitor?
Ripple voltage, in the presence of a filter capacitor, is inversely proportional to load resistance. If the load were zero (resistance infinite), then there would be no ripple voltage. As the load increases (resistance decreases), the ripple voltage increases. The ripple waveform will appear to be sawtooth, with the rising edge following the input AC from the diode's conductioin cycle, and with the falling edge either being linear or logarithmic, depending on load. If the load is resistive, without a regulator, the falling edge will be logarithmic. If the load is constant current, such as with a regulator, the falling edge will be linear.
Why is the graph between load and deflection a straight line?
Because load and deflection are directly proportional to each other
What happens to a beam when force is applied?
The beam will deflect in the direction of the load This is Hooke's law, which states that load is proportional to deflection
What is the difference between inductive coupling and capacitive coupling?
A capacitor is a device that resists a change in voltage, proportional to current and inversely proportional to capacitance. dv/dt = i/c An inductor is a device that resists a change in current, proportional to voltage and inversely proportional to inductance. di/dt = v/l In an AC circuit with capacitive loading, the current waveform will lead the voltage waveform; while with inductive loading, the current waveform will lag the voltage waveform.
What is the amount of blood pumped by your hear each minute?
Depends on the stroke volume (how much blood your heart pumps per beat) and heart rate. This is different for everybody and depends on activity level. Heart Rate x Stroke Volume = Amount of Blood pumped/minute
Is the length of time an electrical load is on proportional to power or energy?
Power (watts) is amperes times voltage, or joules per second. Energy is joules, or watt-seconds. The length of time an electrical load is on is proportional to energy, not power.
What are 3 important factors affecting stroke volume?
Venous return controls EDV (end diastolic volume) and thus stroke volume and cardiac output. Venous return is dependent on: - blood volume and venous pressure - vasoconstriction caused by the sympathetic nervous system - skeletal muscle pumps - pressure drop during inhalation
