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 .
