Tried to take a super heavy object up a flight of stairs ? WHAT HAPPENED. Example. Have you ever . Tried to cut a cake with out a knife?. Example. Have you ever . tried to unscrew a nut, bolt, or screw from something with your bare hands and discovered that it was just too tight to loosen even if you had a good grip? .
The Big Idea of this Investigation. A simple machine is a mechanical device that makes work easier by magnifying, modifying, transferring, or changing the direction of applied force. Simple machines are the elementary "building blocks" of which all complicated machines are made..
By:. Drew Harris. Simple machines. The basic machines that make up other machines are called . simple machines. . There are six of them. They are lever, pulley, wheel and axle, inclined plane, screw, and wedge. All these machines help us move things by changing the size of the force applied, the direction of the force, or both at once. .
The . block . in the diagram below . is on a smooth table and is being pulled by a force of 8N to the right and by a force of 5N to the left. What is the acceleration of the block?. Lesson Objective: RF=ma with pulleys.
Machines. Lesson 7. A compound machine is a machine made of two or more simple machines. The complexity can range from being very simple to very complex. . Domestic . Machines. A . common example of a domestic compound machine is nail clippers. A nail clipper contains two levers. A second class lever and a third class lever. The cutting blades themselves are also simple machines as they are inclined planes. .
