SIMPLE MACHINEINCLINED PLANE

Inclined Plane is flat surface that connect two places with different height

Advantage of inclined plane is force that we give is less

Disadvantage of inclined plane is the road is longer

Example of inclined plane in our daily life can we see in:

parking lot a board to lift a thing from

floor to the truck the way to the top

(puncak)

INCLINED PLANEEXAMPLE OF INCLINED

PLANE

MeCHANICAL ADVANTAGE

W = burden weight (kg)F = force (N)s = the long of the road (meter)h = height of inclined plane (meter)

Km = =

EXAMPLE OF INCLINED PLANE

S . F = h. w

F = x W

EXAMPLE PROBLEM

1. A box has mass of 100 kg will be moved to the top of table with 2 m in height. If the move process use oblique board with 5 m in long, calculate the force to move the box!

MeCHANICAL ADVANTAGE

2. A box with 500 N in weight will be pushed through an oblique board with 4 m in long and 1 m in height, calculate :

a) Force that neededb) Mechanical Advantagec) Work that is done

PROBLEM SOLVING 1EXAMPLE PROBLEM

Known : m = 100 kgh = 2 ms = 5 m

Ask : F

Solution : S . F = h . W 5 . F = 2 . 1.000

F = 400 N
