Mechanical Systems Lesson 1 & 2 Flashcards
What are some examples of simple machines
Wheel and Axle, Levers, Incline Plane, Screw, Wedge
What is a Simple Machine
they change the size and direction of forces.
Parts of a simple machine
Effort Force
Load
Effort Arm
Load Arm
What is a Lever
changes the direction of forces
You need fulcrum,effort,and a load to make a lever
Examples of Levers
Scissors
what does FLE 123 Stand for
1st Fulcrum 2nd Load 3rd Effort
What is work
Work is when there is a force used on an object that moves the object
What is work measured in
Joules (J)
What is work input
Work you do on a machine
What is work output
work that the machine dose on the load
What is mechanical advantage
similar forces created by a machine made for to the machine
why dose a machine never dose more on the load than you do on the machine
The law of conservation of energy
What is the law of conservation of energy
energy can not be created or destroyed it can only change forms
Incline planes
lessens the force you need to apply to lift something
The wheel and axle
-2 turning objects attached to each other at there centers
-can generate speed requires a huge effort Force and produces a smaller force on the load
