A lever is a simple machine made of a rigid beam and a fulcrum. The effort (input force) and load (output force) are applied to either end of the beam. The fulcrum is the point on which the beam pivots. When an effort is applied to one end of the lever, a load is applied at the other end of the lever. This will move a mass upward. Levers rely on to...
There are three types, or classesof levers. In a first class lever, the fulcrum is located between the load and the effort. If the fulcrum is closer to the load, then less effort is needed to move the load a shorter distance. If the fulcrum is closer to the effort, then more effort is needed to move the load a greater distance. A teeter-totter, a c...
In a second class lever, the load is located between the effort and the fulcrum. If the load is closer to the fulcrum than the effort, then less effort will be required to move the load. If the load is closer to the effort than the fulcrum, then more effort will be required to move the load. A wheelbarrow, a bottle opener, and an oar are examples o...
In a third class lever, the effort is located between the load and the fulcrum. If the fulcrum is closer to the load, then less effort is needed to move the load. If the fulcrum is closer to the effort, then the load will move a greater distance. A pair of tweezers, swinging a baseball bat or using your arm to lift something are examples of third c...
Sep 29, 2024 · This technology is called hydraulics and it's used to power everything from car brakes and garbage trucks to motorboat steering and garage jacks. Let's take a closer look at how it works! Photo: This crane raises its giant boom into the air using a hydraulic ram. Can you spot the ram here?
A mobile laboratory is a laboratory that is either fully housed within or transported by a vehicle such as a converted bus, RV, or tractor-trailer. [1][2] Such vehicles can serve a variety of functions, including: Science education. Science research. Air, water, and soil analysis and monitoring.
No one, not even a very strong human, is strong enough to lift a truck. However, our brains are smart enough to create a tool that can lift heavy objects for us: hydraulic lifts! You find them in body shops, on skyscraper construction sites, in wheelchair lifts, and in dentist chairs, and you will even build one in this activity!
Most compound machines, especially in the transportation industry, are far more complex than bicycles or wheelbarrows. Planes, trains, cars, and trucks are compound machines built from thousands or tens of thousands of individual components, many of which are simple machines.

Think of all the big trucks that are used to transport materials. Some of these trucks have lifts — like garbage trucks — that work like levers to unload materials. Ancient and modern day engineers use the concept of balanced and unbalanced forces to move large and heavy materials.
