Why does the input force have to be greater than the force needed to lift the bale?
Friction increases the effect of the input force
How a wedge changes a input force?
A Wedge changes an input force by a change when a mechanical advantage increases as it becomes longer and thinner.
How would the input force needed to push a wheelchair up a ramp change if you increase the height of the ramp but not its lenght?
The effort needed would increase.
Why are you doing the same amount of work lifting a box or pushing it up a long ramp?
because the long ramp decreases the force you need to lift an object, but increases the distance you must move the object
Number of times that a machine increases the input force?
Increasing the distance between the load and pivot increases the work output of a machine.
How would the input force needed to push a wheelchair up a ramp change if you increase the height of the ramp but not its length?
The input force would increase as the height of the ramp increased. It wouldn't matter the distance. Ask me another one.

What is the input and output force of a handicapped ramp?
The input force is where you put force in. This will be the push with the perosn in the wheelchair. The output force is...um...um....um........um..oh right. The output force it where see ya. nvm
What is mechanical advantage?
The number a machine increases the input force.
How a wedge changes a input force?
A Wedge changes an input force by a change when a mechanical advantage increases as it becomes longer and thinner.
How would the input force needed to push a wheelchair up a ramp change if you increase the height of the ramp but not its lenght?
The effort needed would increase.
Number of times that a machine increases the input force; equal to the output force divided by the input force?
Yes. The result of that calculation is the machine's mechanical advantage.
How an inclined plane increases the force without changing the amount of work done?
because going up a ramp takes less force
How does a ramp help to make work easier?
A ramp makes work easier by letting you elevate an object with less input force.
