Science: Inclined Plane, Wedge, and Screw
Wedge
A double inclined plane
Inclined Plane
A ramp or slope
False
A screw is simply a form of a wedge
Efficiency
AMA/IMA
Effort
An inclined plane reduces the______ needed to move a load vertically
Screw
An inclined plane wrapped around a cylinder
Ideal Mechanical Advantage/ IMA
Length (the effort distance) of the ramp divided by its vertical height (the resistance distance)
Internal
On the inside
External
On the outside
Actual Mechanical Advantage/ AMA
The Resistance force divided by the effort force
Friction
The efficiency of the wedge is low because of....
de
The effort distance
Fe
The effort force
dr
The resistance distance
Fr
The resistance force
Angle/Slope
To increase IMA, decrease the....
