The ideal mechanical advantage is calculated as: Ideal_Mechanical_Advantage = distance_moved_by_effort / distance_moved_by_load. It is ideal because it ignores real world factors like energy lost through friction. So an Ideal Mechanical Advantage (IMA) of 7 means that the machinery amplifies the applied effort by 7. For example, a 7 kg load can be balanced using a block-and-tackle arrangement (which has 7 ropes supporting the load block and thus an IMA of 7) using only 1 kg and lifted by applying slightly more than 1 kg. In the real world, there is friction between the pulleys and their bearings so that more real effort is required before the load moves and the real Mechanical Advantage of the above block-and-tackle arrangement is less than 7.
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.
In real machines, there is always friction that reduces the efficiency of the machine.This reduces the mechanical advantage because some of the input force has to be used to overcome the force of friction in the machine.To reduce friction in the machine, you could add a lubricant such as oil.
Advantages- Speed- Analyse large amounts of data- Takes less timeDisadvantages- Complexity of the code can cause problems- Programs are liable to bugs which may effect the dataThese are but a few reasons
Contact the University, they will check their records and issue you a replacement diploma.
I want to know "Fake diploma certificate , of the university I graduate from, I lost my original in a house fire, burn everything to the ground. Hofstra University in Hempstead NY can't find a duplicate copy on the micro film for 1965 May 14, 1965.
How to get my lost employment registration no.
I have british citizenship but I have lost my certificate where can get a replacement?
no
Yes
I am ignacio cuevas from philippines ,my original high school diploma was lost ,were can i get anoter copy and how to get?
i have my registrition no.how can i get my irda certificate?
When mechanical energy is lost to friction, it is converted into thermal energy due to the heat generated by the friction. This thermal energy dissipates into the surroundings, which is why the original mechanical energy is no longer in its mechanical form.
Think about where you lost it, and start by looking there.
I lost when we shift another house
Contact the issuing agency for the certificate.
