It depends on how you arrange the pullies and what you mean by 'three'.
A pulley block can have 3 sheeves, it would have to be used in conjunction with another pulley block with either 2 or 3 sheeves and rigged to advantage or disadvantage.
Or you could have 3 pulley blocks with a single sheeve in each and each one acts on the hauled part of the other, in tandem.

The amount by which a machine multiplies an input force is called?
mechanical advantage
What does the output force divided by the input force equal?
Efficiency of a machine or mechanical advantage
What does IMA stands for in physics?
ideal mechanical advantage
How does mechanical advantage differ from 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 type of pully that does not have a mechanical advantage is?
The simple pulley is the type of pulley that does not have a mechanical advantage.
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 actual mechanical advantage compare with ideal mechanical advantage?
The actual mechanical advantage is usually less, due to losses.
What is the mechanical advantage of a ramp What is the mechanical advantage of a ramp standing straight up?
The mechanical Advantage is FORCE TIMES DISTANCE
The amount by which a machine multiplies an input force is called?
mechanical advantage
What does the output force divided by the input force equal?
Efficiency of a machine or mechanical advantage
What is the mechanical advantage of a lever?
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
What is a Mechanical advantage equal to?
Mechanical advantage the resistance force. Mechanical advantage is equal output force divided by input force.
What does mechanical advantage equal?
Mechanical advantage equals resistance force.
What is the Mechanical Advantage Formula?
Mechanical Advantage: F(out)/ F(in) Actual Mechanical Advantage is the ratio of Force outputed to Force inputed. (AMA=Fo/Fi) Similarly, IMA (Ideal Mechanical Advantage) = di/do
What is true about the mechanical advantage of a machine?
it is less than the ideal mechanical advantage
What is the mechanical advantage of 775?
775 is a number, not a machine. It, therefore, has no mechanical advantage.
What are some ideal mechanical advantage examples?
Mechanical Advantage = Effort/Load
