WebGrade 8 Mechanical Systems Topic 1: Mechanical Advantage Mechanical advantage is the comparison of the force produced by a machine to the force applied to the machine. – PowerPoint PPT presentation Number of Views: 181 Avg rating:3.0/5.0 Slides: 21 Provided by: Prange Category: Tags: grade levers mechanical systems less You already know that: 1. If the input force is smaller than the output force, there is a mechanical advantage. You can say the mechanical advantage is bigger than 1. 2. If the input force is bigger than the output force, there is not a mechanical advantage, but rather a distance advantage. You can say the mechanical … See more A lever can change a large movement with a small input force into a small movement with a largeoutput force. When you use a bottle opener, you use a small input force to pull up the long … See more You can also use a lever the other way around. You can use a big input force over a small input distance. This gives a smaller output force … See more Second-class levers have the fulcrum at one end and the input at the other end. The output is between the input and the fulcrum. A second-class lever always gives a mechanical advantage. The input is always further … See more The bolt cutter in Figure 17 has two pairs of linked levers that are connected to each other. Figure 2 at the start of the chapter shows the movement of the parts of a bolt cutter. 1. The pair of … See more
