What are the units for actual mechanical advantage?
No units. It is a ratio
What is a mechanical adventage?
Mechanical Advantage;The ratio of load and effort is called mechanical advantage of any machine.Mathematical Formula Of Mechanical AdvantageMechanical Advantage = Load / EffortUnit Of Mechanical AdvantageAs mechanical advantage is the ratio of two forces, therefore it has no unit.
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.
Why does a fixed pulley have a mechanical advantage of one and a movable pulley has a mechanical advantage of two?
we find mechanical advantage of pulley by using principle of lever. according to this moment of effort is equal to moment of moment of load. As in this case effort arm is equal to load arm. so mechanical advantage is equal to one. but we know we can never finish friction between rope used and pulley so mechanical advantage is less than one
Which is equal to the ideal mechanical advantage of a pulley system?
It only takes half the effort to move an object but twice the distance
How do you calculate the mechanical advantage of any machine if you only know the forces?
The ratio of the output to input forces may help you there.
Would the mechanical advantage change on the moon?
-- Look at the formulas you use in order to calculate the mechanical advantage of any device. -- If the force of gravity or the weight of any part of the machine appears in any of those formulas, then the value of the formula depends on the local gravitational environment, and it depends on which planet the machine is on. -- If neither of them does, then it doesn't.

How can you increase mechanical advantage of a gear system?
A mechanical advantage occurs when a tool such as a hammer is used that increases the amount of force being applied without increasing the effort of the person using the tool. To increase mechanical advantage, you could use a bigger hammer to increase output force.
What effects the mechanical advantage?
mecanical advantage make to do any work easily
What is a mechanical impression?
A mechanical impression is any indentation on an object caused by a machine
How is the mechanical advantage of a movable pulley determined?
The method to calculate mechanical advantage is easy to remember and is necessary when rigging the assembly to accomplish the job. The mechanical advantage of a rigging that will require upward pull can be determined by counting the number of rope lengths running between engaged pulleys and those doing the work. Likewise, if the assembly will require downward pull, count the ropes and subtract one to get the mechanical advantage number. The subtraction is necessary because with the fixed pulley, the downward pull equals the load on the other length of rope so the last "pull" rope does not provide any mechanical advantage.

How to calculate the electrical energy for machine?
Electricity does not occur in natural state. It has to be generated by converting one form of energy into electric energy. The electric energy of any machine can be calculated by subtracting the all losses occurring in a machine (electrical, mechanical and magnetic) from total input power or energy.
Name any four mechanical equipmrnts?
Hydraulic machine, car engine, a pulley and a pump is an example of the mechanical equipment.
