Uses of Tools in Life

A machine is a tool or hardware used to help with doing certain task more easily and quickly. Machine acts as a tool that uses power to apply force and control movement to perform an action. There are various types of machines ranging from simple machines and complex machines.
 
10.1  Uses of Tools in Life
 
  • There are several simple machines that have different functions combined on one tool to enable the tool to function perfectly.
 
Simple tools and machine function combinations

  1. The wheels and axles on the rotor make it easy to rotate the tool
  2. The rotor needs to be rotated so that the wedge can work to sharpen the pencil point
  3. The wedge on the mechanical pencil sharpener allows the pencil point to be sharpened

  1. Nail clippers are a combination of levers and wedges
  2. The load position is on the nail while the force position is on the thumb
  3. The fulcrum is a point located between the load and the force that allows the nail clipper to be used

  1. The gears on the clock work to move and rotate the clock
  2. Screws are used to fasten the components of the watch
  3. The wheels and axles on the rotor also serve to set the clock
 
The importance of simple machines combination
  • The combination of several simple machines that appropriate on a tool is important to ensure that the tool can function properly
 
The importance of characteristics of sustainable tool creation
  • The use of tools in various fields can help facilitate & speed up work in daily activities
  • The characteristics of sustainable tool creation are important to simplify & speed up work, save time, cost & energy
  • The characteristics of sustainable tool creation are as follows:
  1. suitable material
  2. longer tool lifespan
  3. easy to maintain
  4. low cost and economical
  5. eco-friendly
  6. safe to use
