How does increasing the number of pulleys affect the ideal mechanical advantage and efficiency of pulley system?
Ideal mechanical advantage is the mechanical advantage when the efficiency of the pullefy system is 100%. It is a constant for that system of pulleys. Therfore it is not affected by increasing or decreasing the load.The MA of a pulley is equal to the number of supporting ropes.If the load is supported by one rope , the M.A of the system is 1. Efficiency is 1 for ideal pulley ( No loss of energy due to friction)If the load is supported by two ropes , the M.A of the system is 2. But Efficiency is still 1 for ideal pulley ( No loss of energy due to friction)If the load is supported by three ropes , the M.A of the system is 3. Efficiency is still 1 for ideal pulley ( No loss of energy due to friction) .And so on.Read more: How_does_increasing_the_load_affect_the_ideal_mechanical_advantages_and_efficiency_of_a_pulley_system
Can you use a 12 v 1000 ma AC adaptor instead of 12 v 700 ma AC adaptor?
Yes, the 1000 mA has more that enough capacity to operate a 700 mA device. If the 700 ma adapter was original equipment with the device it was to charge, then the device is more than likely drawing about 500 to 600 mA. Look on the device's nameplate and you should see the mA draw.
Mechanical advantage of a compound machine?
MA = Revolutions of input shaft / Revolutions of output shaft. (Input torque * MA) * efficiency = Output torque Note 100% efficiency = 1.0
Can you use 5 v 1200 ma charger for device requiring 5v 700 ma?
yes, it will just charge the device faster..
Can you use a 12v 1a adaptor for a 800ma?
Yes, 1 amp is equal to 1000ma and it will be able to operate a 850 ma device.
What is the MA of a 1st class lever that is 24 cm long and the fulcrum is 0.5 cm from the resistance?
The ideal MA is 47.
What is input current if output voltage is 48V and output current is 350 mA and load of 15Watt?
A: Assuming 100% efficiency 320 ma
Actual mechanical advantage is always better then theoretical MA why?
"Better" is an interesting word. I would guess that theoretical MA beats actual MA any day of the week. Some energy is lost in friction.
How does the size of a ideal mechanical advantage compares to the mechanical advantage?
This is because the actual mechanical advantage is the actual calculation found after dividing the effort force by the output force. Ideal mechanical advantage is what many people would call and estimate. When estimating mechanical advantage, the numbers are always rounded. This makes actual mechanical advantage less. Sources: Science teacher ------------------------------------------------------------------------------------------------------------------ The answer above is incorrect. The ideal mechanical advantage (IMA) is usually less than the mechanical advantage (MA) in a given machine because of the friction acting on the machine. There will always be some frictional resistance that increases the effort necessary to do the work.
Can you use a 1300mA universal adapter for a 200mA device?
Yes, the maximum that the adapter can deliver is 1300 mA or 1.3 amps. The maximum that the device will draw is 200 mA or .2 of an amp.
Can you use a 1A adapter instead of a 500mA adapter?
A one amp adapter is the same as a 1000 mA adapter. If your device requires 500 mA to operate then there is ample capacity in the adapter to operate a 500 mA device. Be sure to match the type of voltage AC or DC from the adapter to the driven device. Both have to be the same.
Can you use 500 ma power adapter on a device that requires 625 ma?
No, the capacity of the device is too large. The adapter will heat up and may even burn its internal windings open.
