How would you measure the force needed to lift 50kg of shingles onto a roof using a pulley?

50 kg (on Earth) weighs about 110 pounds. If you're using a simple, single
pulley with a rope passing over it, then that's the pull you need on the rope to
lift the bundle of shingles. If you're using a block and tackle arrangement of
multiple pulleys, then you'll get away with much less pulling force on the rope,
but you'll have to pull the rope much farther.

How did the pulley affect the amount of force needed?
A pulley is a force multiplier. (it swaps force for distance).
Which machine changes the direction of force needed to do a task without changing the size or force needed?
A pulley can do that.
Which machine changes the direction of force needed to do a task without changing the size of force needed?
A pulley can do that.
How does a movable pulley reduce the input force needed to lift a weights?
a lever
What is a Disadvantage of a fixed pulley?
The pulley does not reduce the force needed for lifting an object. Also, the pulley can't readily move to another location, but that may be an advantage depending on the application.

What are the differences between a fixed pulley and a moving pulley and how do each of them change work?
The difference between a fixed pulley and a movable pulley is, the wheel of a fixed pulley does not move because the wheel is attached to a wall, ceiling, or other object. Unlike a fixed pulley, a movable pulley's wheel does move. The wheel on a movable pulley is not attached to a wall or other object. A fixed pulley changes work by changing the direction of a force. A movable pulley changes work by reducing the input force needed to lift heavy objects. A movable pulley changes the direction of the input force and reduced it. A movable pulley also increases the output force.

Why is a pulley a force multiplier?
Why are pulley force multipliers? Pulley are force multipliers because they expand the distance over which it operates.
Is mass a measure of the gravitational force of a object?
No, mass is the measure of matter in an object. Weight is the measure of gravitational force needed to keep the object grounded.
What is the purpose of a inclined plane with a pulley?
To reduce the amount of force needed to carry objects into the truck k12
