Rotational Motion: Can 1 Force Make It?

AI Thread Summary
A free body can experience rotational motion due to a single force, but this motion is not purely rotational. If the force is applied through the center of mass, it results in pure linear motion. Conversely, if the force is applied off-center, the body will undergo both rotation about its center of mass and linear motion. To achieve rotation without linear motion, the force must be divided into a "couple," which consists of two equal and opposite forces spaced around the center of mass, along with a force through the center of mass for linear motion. Properly balancing these forces is essential to ensure the correct changes in momentum and energy. An unbalanced free body will temporarily rotate or move toward the attractive force until equilibrium is reached, but sustained peak cycling of this phenomenon has not been demonstrated.

It is possible for a free body to make rotational motion with the effect of one only force?

Not "pure" rotational motion. If the single force happens to be through the center of mass then you would get pure linear motion. If the single force is applied on a line not through the center of mass, then you will get a combination of rotation about the center of mass and linear motion. You would need to divide the force into a "couple"- a pair of equal but oppositely directed forces (so they add no linear motion) equally spaced about the center of mass to create the rotation- and a force through the center of mass to create the linear motion. You would need to set the forces so that the change in total momentum and energy is correct for the force applied.
 
An unbalanced free-body will tend to rotate or otherwise move towards its attractive force. But this is only temporary(until balance is achieved). Sustained peak cycling of this has never been demonstrated to my knowledge.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
