Since the question clearly states that the machine only changes the direction there can be no mechanical advantage gained.
In order for a machine to have a mechanical advantage greater than 1, the machine must be able to change two or more of these factors:
when you change the direction of a force more of the applied force can be used to move the mass at the other end.
on a x,y plot if your pulling a force up a ramp you want all the force to be applied parallel to the ramp so that none of the force is pulling the mass down at the ramp,
similarly you don't want to be pulling the object off the ground and across the ramp or your wasting applied force to lift the mass.
(hope this answers your question. its hard to explain adequately without being able to graph it)
The ideal mechanical advantage is (the output force) divided by (the input force).
You just told us that your machine doesn't change the input force, so that quotient is ' 1 ' .
if only the direction changes,the input force will be the same as the output force.the mechanical advantage will always be 1.
If the machine is loss-less, the mechanical advantage is 1. (i.e. nothing gained)
Since all real machines do have losses you can expect .9 - .97 if it is well built.
It has an advantage of one. :)
Mechanical Advantage=1
It's one (1.0).
There are three types of levers namely first, second and third class. First class levers can change the direction of input force.
single fixed pulley changes the direction of the applied force, you pull down, the object goes up.
It increases the applied force and changes its distance and direction. -Novanet
The fixed pulley only changes the direction of the force applied.
Movable pulley is attache to the object you are moving while Fixed Pulley changes direction of the applied force.LaDy_caRoLi "Christine carren alcantara"
if only the direction changes,the input force will be the same as the output force.the mechanical advantage will always be 1.

Thew pulley changes the direction of the effort force.
A fixed pulley does NOT multiply the effort force or have a mechanical advantage. It only changes the direction of the effort force. A free pulley multiplies the effort by two. this means the free pulley has a mechanical advantage of 2.information from:www.mhscience02.com
A single pulley alters the direction of the input but confers no mechanical advantage.
A single pulley has no mechanical advantage, it just changes direction.
A single pulley normally gives no mechanical advantage: it changes the direction of the force required.With 2 pulleys the rope or cable is looped around both so that there are several lengths of it pulling the mass. If there are k such strands, each one bears 1/k of the total mass so (if you ignore friction) there is a mechanical advantage of k.____________________________________________The mechanical advantage of two pulleys mounted in a block and tackle is twice the applied force. The lead rope needs to have half the force applied to move the same load, but twice the distance must be moved on the lead rope such that the same total force is applied to the load.
Of a single pulley wheel, only that it changes the direction of the force ie: from overhead. > On a block and tackle system, 2 or more pulley wheels are used in a certain way to produce mechanical advantage. The simplest type of block and tackle offers a mechanical advantage of 2
A single pulley simply changes the direction of the force. A block and tackle or multiple pulleys can offer a mechanical advantage - same as an inclined plane. For the same mechanical advantage, a pulley system may be better because of lower friction.
It changes the direction of an applied force.
