Ideal mechanical advantage is a numerical ratio. It's a naked number without a unit.
Increase the advantage.
The ideal (not idea) mechanical advantage is 30/4 = 7.5
Input and output (of energy)

radius
The mechanical advantage is a dimensionless ratio. It's just a number, with no units.
No, the ideal is without friction.
The ideal mechanical advantage of a ramp is directly related to the height of the ramp. The ideal mechanical advantage is calculated as the ratio of the length of the ramp to its vertical height. So, the higher the ramp, the greater the ideal mechanical advantage.
Mechanical Advantage = Effort/Load
it is less than the ideal mechanical advantage
Mechanical advantage is determined by physical measurement of the input and output forces and takes into account energy loss due to deflection, friction, and wear. The ideal mechanical advantage, meanwhile, is the mechanical advantage of a device with the assumption that its components do not flex, there is no friction, and there is no wear.
The actual mechanical advantage is usually less, due to losses.
The ideal mechanical advantage of the bar is 5.
Increase the advantage.
The kind of pulley has an ideal machanical advantage of 2 is called "Movable Pulley". From, Bryan Hollick
The formula for determining ideal mechanical advantage is: IMA = (effort distance / load distance) or IMA = (input force / output force).
Mechanical advantage is the ratio of the output force produced by a machine to the input force applied to it. Ideal mechanical advantage is the theoretical ratio of the output force to the input force, assuming no energy losses due to friction or other factors. In reality, actual mechanical advantage is always less than ideal mechanical advantage due to factors like friction and inefficiencies in the machine.
