10.3.3 Design combinations of mechanisms to achieve specific tasks.

Consider the following tasks:
  • alter the axis of rotation
  • change the type of movement
  • increase force and decrease speed
  • decrease force and increase speed.

Draw one mechanical system for each of the above specified tasks. Also, explain how it works in a product or system.
