What forces are involved in an inclined elevator boat lift?

AI Thread Summary
The discussion focuses on the forces acting on an inclined elevator boat lift, particularly the torque exerted by the boat's weight relative to its distance from the inclined arm. It is noted that this torque remains constant as the boat moves up and down the lift. The inquiry raises concerns about whether additional forces could increase the torque and affect the stability of the lift as the boat's height changes. The setup's stability is questioned, especially regarding the potential for tipping when the boat is positioned higher. The inclined arm's anchoring on the seawall and its underwater support are also mentioned as factors in the overall stability of the system.

Hi,
I have a question regarding the forces involved in an inclined elevator boat lift. Attached is a diagram of the setup. I was wondering what forces are involved. I know that there is a torque that is exerted on the inclined arm equal to the weight of the boat times the distance of the center of the boat from the inclined arm. This torque does not change as the boat moves up and down the lift. However, are there other forces involved that would cause a greater torque on the inclined arm the higher the boat moves up and down the lift? For example, is the setup more likely to tip over when the boat is higher up the lift? Or is the setup just as stable regardless of how high the boat is. Also, the inclined arm is resting on the seawall and is driven down into the ground underwater. Thank you for any light you can shed on this :) attached is the diagram

I approved the attachment. Is this a homework problem? If so, I can move it to the Physics homework forums.
 
thank you for approving it. this is not a homework problem. it is just a curiosity thing thank you
 
Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
