Why does the shaping tool move faster during the return stroke?
During the return stroke it does not remove any material, it is an idle stroke so to improve the cutting efficiency it will move faster during the return stroke. Pradip Kotak.
What is a snap choke core?
It is a ferrite core over coax cable, AC or audio cord. It prevents electro-magnetic interference (EMI) and cuts down on radio-frequency interference (RFI).Prevents electric magnetic interference (EMI) and cut down on radio frequency interference (RFI)Simply snap it over any coax cable, AC or audio cordRoSH compliant
Is there a backup wrench made for castellated nuts?
No, they are made for use with regular or box wrenches. In over 40 years of working t=with them,I've never seen any 'backup wrench' and can't even think why you would want one.
What is vacuum pump?
A vacuum pump is any device which does work to transfer air from one volume to another volume, and thereby reducing the pressure of the first volume. There are several different types of vacuum pumps available, each operating over different pressure ranges.
What is the difference between normal flowrate and Actual flow rate?
Normal flow is 100% of the flow you actually expect. Rated flow is the maximum safety factor times the normal flow. i.e. for a maximum safety factor of 1.2 Normal flow = 100 gpm Rated flow = 1.2*100 gpm = 120 gpm Safety factors are applied to ensure a piece of equipment has some flexibility of operating conditions in its application. The minimum flow is the minimum safety factor time the normal flow i.e. i.e. for a maximum safety factor of 0.5 Normal flow = 100 gpm Rated flow = 0.5*100 gpm = 50 gpm If sized properly a pump specified in this way could operate at any point between 50 and 120gpm with no problems.
Can a car have a 100 percent efficiency?
No. Nothing mechanical can ever have a 100% efficiency by any physical evaluation.
What force could increase the resistance of all the PULLEYS?
Any force that will not allow the pulley to operate to peak efficiency
What efficiency is assumed when calculating the ideal mechanical advantage?
The assumed efficiency is 100% without any friction
Why a normal machine could not have the mechanical efficiency of 100?
Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.
Why can't mechanical efficiency be over 100 percent?
The mechanical efficiency can't be over 100% because a type of energy is always lost. For example, it can be lost as heat, sound or even light. When you use a light bulb, it produces light, but heat is lost in the process. See what I mean! In most cases, heat is lost due to friction. the work put out by a machine is always less than the work put into a machine to do the work. Therefore no machine is 100% efficient. As well.... Efficiency is (power out/power in) x 100. To get an efficiency of *more* than 100%, the machine must give more power out than is put in. No machine has ever been demonstrated that does this, and until someone can show this result (power out *more* than power in), we know that any machine has an efficiency less than 100%.
Why doesn't any system have 100 percent efficiency?
frictionIn real machines, as opposed to ideal machines, there is always friction that reduces the efficiency of the machine. Lubricants like oil can be used to reduce friction and improve efficiency.
What are the si units for efficiency?
Efficiency is adimensional, meaning there is no associated unit, just a number - and the number should be the same in different measurement systems. Efficiency can be any number between 1 (equivalent to 100%) and 0 (equivalent to 0%).
What is 32 over 100 as a percent?
Any number over 100 is automatically that percent. For example, 32 over 100= 32% 50 over 100= 50% 98 over 100= 98%
What is the maximum efficiency any machine can have?
Mathematically, efficiency = (energy output) divided by (energy input) as a percentage. As if we couldn't figure this out for ourselves, one of the laws of Thermodynamics formally tells us "You can't get more energy out than what you put in." Applying this law to the formula for efficiency, it says that the maximum possible efficiency is 100%. However, the next law of Thermodynamics says "You can't even get that much out."
What type of efficiency would a simple machine have if the output work of the machine equals the input work?
Although it is impossible for any machine to have an efficiency of 100%, it would in this case be 100%. Studies have shown that when ever there is motion, there has to be a loss of energy due to friction. So any rotating machine, big or small will have losses.
How many support ropes are on this pulley?
there can be any amount of ropes on a pulley
Can a machine be more than 100 percent efficient?
100% efficiency would mean that the machine is able to transform energy from one form into another without any loss of energy from the system in the process. For it to have greater than 100% efficiency, it would have to somehow generate additional energy, not contained in the system, in the process, and this is not possible.
