5. Forces self-eval q's

What force (in Newtons) is required to act on a rocket of 2,000 kg mass to make it travel in free space with a uniform rate of acceleration of 10,000 meter/s²?

20 million Newtons

Which of Newton's Laws Of Motion states "for every action there is an equal and opposite reaction"?

Newton's third Law

Which of Newton’s Laws of Motion states "anybody moving uniformly in a straight line or at rest will remain in uniform motion or at rest, unless acted upon by some outside force"?

Newton's first Law

An inclined plane cut in a spiral around a shaft is the:

screw

The force applied to a machine is:

effort

Simple machines that are extensions of the inclined plane are two (2) of the following:

wedge and screw

The simple machine that consists of a rigid body, typically a metal bar pivoted on a fixed fulcrum is a:

lever

A third class lever can be defined in the following way:

the effort is between the resistance and fulcrum

If a box was pushed up a ramp 0.80 meters, and the ramp was 0.27 meters off of the ground, what is the ideal mechanical advantage (IMA) of this simple machine?

2.96

If the ideal mechanical advantage IMA is 2 and the effort distance is 0.10 meters, what would the resistance distance be?

0.05m

If a machine has a Distance Effort of 1.00 meters and a Distance Resistance of 0.37 meters along with a Resistance of 5.20 Newton, what is the machine's ideal effort?

1.93 Newton

Determine the ideal effort of a simple machine if the resistance is 5.4 Newton and the ideal mechanical advantage is 3.08

1.75

An object weighs 5.20 Newtons. When lifted by a pulley 16.00 Newton force is needed to move the resistance. Identify the actual effort?

16.00 Newton

It takes 2.20 Newtons to move an object that weighs 5.20 Newtons. What is the Actual Effort involved?

2.20 Newton

Given the resistance to be 5.70 Newtons and an effort of 2.14 Newtons, what is this machine's AMA?

2.66

Determine the actual mechanical advantage of a simple machine if the resistance is 5.4 Newtons and the actual effort is 2.8 Newtons
