With a pulley system a force of only 50 lb can lift a 500-lb weight What is the mechanical advantage if this system is 100 percent efficient?

Your question has a basic flaw. With a system of pulleys the ratio cannot be 10, it can be only a power of two: 2, 4, 8, 16...
There is no mechanical advantage, it's only a matter of convenience: using a force of 50 lbs one can lift a weight of 400 lbs, but in order to do that one has to pull the rope for a distance equal to 8 times the lifting height.

Why does a fixed pulley have a mechanical advantage of one and a movable pulley has a mechanical advantage of two?
we find mechanical advantage of pulley by using principle of lever. according to this moment of effort is equal to moment of moment of load. As in this case effort arm is equal to load arm. so mechanical advantage is equal to one. but we know we can never finish friction between rope used and pulley so mechanical advantage is less than one
What is the mechanical advantage of a stationary pulley?
Its 1 you need more than 1 to improve mechanical advantage i think it's 2 A single pulley means one axel, making the IMA = 1. A double pulley's IMA would = 2, and so on and so forth.
How do you calculate the mechanical advantage of a movable pulley?
use calculator
Type of pulley that has additional numbers of ropes that help to increase mechanical advantage?
Fixed Pulley!!
Which is equal to the ideal mechanical advantage of a pulley system?
It only takes half the effort to move an object but twice the distance
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 the mechanical advantage of the pulley system?
The mechanical advantage of the pulley system is the inertia and friction of the unbalanced and balanced forces acting on the mechanical advantage which is part of the pulley system....
What is the mechanical advantage of systems of pulleys?
The mechanical advantage of the pulley system is the inertia and friction of the unbalanced and balanced forces acting on the mechanical advantage which is part of the pulley system....
What is the mechanical advantage of a fixed and free 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
What is the mechanical advantage of a movable pully?
for one movable pulley you would get a mechanical advantage of 2
What is the mechanical advantage of a fixed pulley?

Why can't a pulley have a mechanical advantage greater than 1?
The mechanical advantage of a pulley can be greater than 1.The efficiency cannot but that is a different matter.
What is the advantage of adding pulleys to a pulley system?
More mechanical advantage.
