Tie a bundle of books with one end of the thread. Attach the other end of the thread with a spring balance and pull the bundle along the inclined plane. Note the reading of the spring balance. Which reading is smaller? ________________________________________________________________ ________________________________________________________________ Why the reading is less in the second case? ________________________________________________________________ ________________________________________________________________ Which will be easier; moving the books using the inclined plane or moving them by lifting straight up and why? ________________________________________________________________ ________________________________________________________________ __________________________________________________________ __________________________________________________________ __________________________ Give different examples of inclined plane? ________________________________________________________________ ________________________________________________________________ Simple Machines Directions: Label each picture as the correct type of simple machine.
