Simple Machines In Activity

Simple Machines  Simple machines are basic machines that are the basis for all other forms of machines.  There are six types of simple machines:  1.

Simple and Compound Machines Simple Machines- the ability to do work Compound Machines- machine made up of two or more simple machines that work together.

Inclined Plane Decreases Input force!!! A flat, sloped surface.

Simple machines 6 types of simple machines, mechanical advantage of each type and compound machines.

Lesson 3: How are work and Motion related?. Work – the result of a force MOVING an object.

Simple Machines There are 6 types of simple machines: the inclined plane, the wedge, the screw, the lever, the pulley, and the wheel and axle.

Machines Making Work Easier.

Classification of simple machines: Simple machines are divided into two families: 1)The Lever family and 2) The inclined plane family.

Levers All levers have a ridged bar that is free to move about the fulcrum (fixed point) when effort is applied All levers have a ridged bar that is free to move about the fulcrum (fixed point) when effort is applied

Levers continued 1 st class has effort (e) then fulcrum (f) then the resistance (r) such as a Tire iron 1 st class has effort (e) then fulcrum (f) then the resistance (r) such as a Tire iron

Levers continued 2 nd class levers has fulcrum (f) then the resistance (r) then the effort such as a wheelbarrow 2 nd class levers has fulcrum (f) then the resistance (r) then the effort such as a wheelbarrow

Incline plane family A slanted surface that changes the size and direction of the force needed. Longer ramp = less force needed A slanted surface that changes the size and direction of the force needed. Longer ramp = less force needed

Wedge Is a modified incline plane or 2 incline plane back to back such as a ax blade or nails (tips) Is a modified incline plane or 2 incline plane back to back such as a ax blade or nails (tips) Turns 1 downward force into 3 side directed forces Turns 1 downward force into 3 side directed forces

Screw An incline plane wrapped around a cylinder. An incline plane wrapped around a cylinder. The gentle sloping threads requires small force to move. The gentle sloping threads requires small force to move.

Compound Machines 2 or more simple machines combined together such as a bicycle- wheel and axle and levers. 2 or more simple machines combined together such as a bicycle- wheel and axle and levers.
