Inclined Plane , Wedge, and Screw
The mechanical advantage of a screw is the distance moved in one full turn divided by the ?
- Distance between threads
Wedge
-A double inclined plane
Inclined Plane
-A ramp or a slope
Screw
-An inclined plane wrapped around a cylinder
A form of the inclined is a ?
-Ax
Examples of an wedge:
-Ax -Chisel -Nail
A major factor in the use of the inclined plane is?
-Friction
The efficiency of the wedge is low because of ?
-Friction
A steep slope requires ? force over a ? distance .
-Greater -Shorter
A screw is a form of?
-Inclined plane
More force over a shorter distance is needed for a ?
-Increase the length of the ramp.
An inclined plane reduces the ? needed to move a load vertically.
-Input force
A nut has a(n) ?
-Internal thread
A form of a wedge is a ?
-Knife
Less effort is used with a ?
-Long wedge
Internal
-On the inside
External

An inclined plane wrapped around a cylinder make a machine called?
-Screw
To increase IMA, decrease the ? of the ramp.
-Slope
A gentle slope require ? force over a ? distance .
-Smaller -Greater
It is easy to split wood with a ?

The ridge forming the inclined plane is called ?
-Thread
A screw is not a simple form of a wedge.
-True
The has very low efficiency.
-True
The mechanical advantage of an inclined plane is length divided by ?
