disa [49]

Answer:

Tommy has a screw whose length is 4 cm and its thread length is 16 cm. What is the mechanical advantage of the screw?
Rus_ich [418]

Answer:

a screw is a simple machine that works as a modified inclined plane. You can think of the thread of the screw as an inclined plane wrapped around the shaft of the screw. The slope of the screw is the distance for one complete rotation while the height of the inclined plane is the distance between the threads, known as pitch. The relationship between the pitch and circumference of the screw gives the mechanical advantage.
