Free Body Diagrams The first step is to draw a Free Body Diagram also called a Force Diagram Free Body Diagram A sketch where a body is cut free from the world except for the forces acting on it In the bridge example the free body diagram for the top of the tower is Free Body Diagram It helps us to think clearly about the forces acting
Pulleys are categorized as a type of simple machine consisting of a grooved wheel and a rope or cable These devices help us to lift heavy loads in an effective manner as well suspend various objects in the air for example a flag Read this ScienceStruck article to know more about the various types of pulley systems and their working mechanisms.
SIMPLE GEAR TRAIN Figure 5 These are typically spur gears as shown in diagram 1 The direction of rotation is reversed from one gear to another The only function of the idler gear is to change the direction of rotation It has no affect on the gear ratio The teeth on the gears must all
19 08 2015 Crushing cans can be a long and hard process when you have a bag with empty aluminum soda or beer cans after a party and although a regular or a semi automatic can make this process a lot more efficient you can still get tired easily after few dozens of aluminum cans compressed So to make this process even more effective some handy people have made their own

20 04 2018 in this video we re going to discuss different types of forces but we re gonna do it in the context of free body diagrams so let s say that I have a table here and I have a block that is sitting stationary on that table what are all of the forces that are going to act on this block well to do that to think about that I can draw Freebody diagram
29 09 2021 In a free body diagram a box is used to represent the object and arrows the forces are drawn outward from its sides Once you put all of this together it s pretty simple to figure out which
Using Newton s second law to conduct a free body analysis of a single object may have seemed difficult enough Analyzing the inter dependent motion of two objects may seem impossible The Physics Classroom takes the mystery out of the topic with a logical presentation of a process for analyzing two body problems An emphasis is placed upon the analysis of Atwood s machines and modified Atwood
