1/4 the output force.
Efficiency of a machine or mechanical advantage
Mechanical advantage is the greater outputted force than inputted force that is generated by using a machine. One example is pulling a pulley to create a much greater output force on the other side that a person could not lift without a pulley.
Depends what the input force is and the mechanical advantage of the pulley system If effort force (input force) is 20 pounds in a 6 pulley system (3 fixed,3 movable) then load force (output force) is 120 pounds As 6 times 20 equals 120 pounds

Efficiency of a machine or mechanical advantage
Mechanical advantage the resistance force. Mechanical advantage is equal output force divided by input force.
mechanical advantage= output force over input force
Mechanical advantage is the greater outputted force than inputted force that is generated by using a machine. One example is pulling a pulley to create a much greater output force on the other side that a person could not lift without a pulley.

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
Mechanical advantage of a fixed pulley
Mechanical Advantage
Mechanical Advantage which is the output force divided by the input force.
mechanical advantage= output force over input force times 100
