Question

I NEED IT ASAP DUE 2 HOURS
You need to write a short essay, of 500 words, that discusses the below points.

1. What are some complex machines that you have encountered in your lives? Do these machines make work easier or harder? How useful are they?


2. Is mechanical advantage always the best way to measure the value of a machine? Why or why not?


3. How are you using the six simple machines in your Rube Goldberg design? What are you going to do to reach your intended goal/purpose of your Rube Goldberg machine?

Answer 1

Answer:

1.

• The lever.
• The inclined plane.
• The wheel and axle.
• There wedge.
• The pulley.
• The screw.

2.

It takes into account the force needed to overcome friction. The ideal mechanical advantage of a machine reflects the increase or decrease in force there would be without friction. It is always greater than the actual mechanical advantage because all machines must overcome friction.

3.

A Rube Goldberg Machine is “a comically involved, complicated invention, laboriously contrived to preform a simple operation.” 2. What are the 6 Simple Machines? A. The 6 Simple Machines are: wedge, screw, lever, wheel and axel, inclined plane and pulley.
