Activity 1.1 Simple Machines Practice is a great opportunity to learn about the basic principles of simple machines and how they work. Simple machines are mechanical devices that use a single force to perform work. They are called simple machines because they are composed of a single element, such as a lever or a wheel and axle.

There are six types of simple machines: lever, wheel and axle, pulley, inclined plane, wedge, and screw. Each simple machine has its own unique characteristics and can be used to perform a variety of tasks, such as lifting heavy objects, moving objects over a distance, or applying force to an object.

The lever is a simple machine that consists of a beam or rod that is supported on a fulcrum. Levers are used to lift or move objects by applying a force at one end of the beam. The wheel and axle is another simple machine that consists of a wheel with a smaller axle attached to it. The wheel and axle can be used to lift heavy objects by applying force to the wheel, which in turn rotates the axle and lifts the object.

The pulley is a simple machine that consists of a wheel with a groove around the circumference and a rope or cable running through the groove. Pulleys are used to lift heavy objects by applying force to the rope or cable, which in turn lifts the object. Inclined planes are sloping surfaces that can be used to lift or move heavy objects over a distance. Wedges are triangular-shaped simple machines that are used to split or cut materials by applying force to the wide end of the wedge. Screws are simple machines that consist of a spiral-shaped rod that is used to hold or fasten objects together by turning it.

In conclusion, simple machines are important tools that we use in our daily lives to perform a variety of tasks. Understanding how simple machines work and how to use them effectively can help us to solve problems and make our work easier. Activity 1.1 Simple Machines Practice is a great opportunity to learn about these essential tools and how to use them effectively.

What is the length of the slope? Sketch and annotate the lever system described above. What is the actual mechanical advantage of the system? Illustrations should consist of basic simple machine functional sketches rather than realistic pictorials. Using the known height and calculated base length, what is the length of the slope of the ramp? Just from a good sketch, however, an engineer can deduce how a mechanism will transform forces and distances from input to output -- from effort to resistance. Using static equilibrium calculations, calculate the length from the fulcrum to the resistance force. What is the ideal mechanical advantage of the system?
