What is the effect on the effort force used when the length of the effort arm is decreased?

The force you are referring to is called torque. here is an example: you have 2 wrenches, one with a short handle and the other with a long handle, and 2 identical bolts. The force required for the longer wrench to turn the bolt is less than the force required for the short to turn the bolt. This is because the longer the handle the greater the Torque and therefore less force needs to be applied.
summary: longer "effort arm"=more torque= less force needed
shorter "effort arm"=less torque=more force needed
I hope this answers your question

When effort force is decreased what must be increased?
the acceleration of the effort force
How does the length of effort arm affect the amount of effort needed to lift an object?
The length of the "effort arm" of the lever clearly has a great influence on the 'effort' the pusher must input to the lever in order to do the job. But in terms of the "work" done ... in the formal sense of Work as defined in Physics = (force) x (distance) ... the length of the effort arm should have no effect on the quantity of work.
What is the formula for the MA of a wedge?
MA= resistance force / effort force = Fr/Fe
In a second class lever why must you exert input force over a greater distance?
If the input force is applied at a greater distance than the length of the effort arm is increased thereby reducing the effort.
What effect does a movable pulley have on the effort force?
that the movable pulley is not easy to help in carrying heavy things
When effort force is decreased what must be increased?
the acceleration of the effort force
When is the effort force decreased in a first class lever?
The effort-to-load force in a first class lever is decreased when the distance between the effort and the fulcrum is less than the distance between the fulcrum and the load.

What force opposes the effort force?
load force and friction oppose the effort force
What does effort forces mean?
The effort force is the force that is applied to an object that causes it to move. The object reciprocates with a resistance force. If the effort force is greater than the resistance force, the object moves.
What type of pully can multiply effort force?
Actually, pulleys cannot multiply effort force. It can only change the direction of the effort force.
What only changes the the effort of the force on a fixed pulley?
The length of travel. (how far you have to draw the rope/cable etc.) The longer you have to draw, the less force you have to use at a moment of time.
If the force squeezing two surfaces together is decreased the force will likely do what?
If the force is decreased, it will likely become smaller, and perhaps also lesser as well. Too.
What happens to the force if the distance between 2 objects is decreased?
Gravitational force would increase as distance is decreased. Because force is inversely proportional to the square of the distance
