# The ideal mechanical advantage of a machine reflects the increase or decrease in force there world be without friction, it is always greater than the actual mechanical advantage because all machines must overcome friction. options: true false moneydee123

Step-by-step explanation: deanazilyiah

I think False hope this helps??? XP

Step-by-step explanation: dhdcchj

Explanation:

Actual and ideal mechanical advantage, how to calculate them and the mechanical ... changes the input force when the machine is actually used in the real world. ... The ideal mechanical advantage is always greater than the actual mechanical advantage because all machines have to overcome friction. tsigler6425

True: the ideal mechanical advantage of a machine is always greater than the actual mechanical advantage because all machines must overcome friction.

Explanation:

For a simple machine, it is possible to calculate two types of mechanical advantage:

1) The Ideal Mechanical Advantage (IMA) is given by where is the resistance arm is the effort arm

The IMA gives the mechanical advantage of the machine if there are no friction forces acting on it, and if all the work in input is converted into work in output with no loss of energy

2) The Actual Mechanical Advantage (AMA) is given by where

L is the load (the force in output)

E is the effort (the force in input)

The AMA gives the real mechanical advantage of the machine. For an ideal machine, Because there is no loss of energy due to friction. because part of the input energy is converted into thermal energy and other forms of energy due to the presence of friction, so it is "wasted" energy.
