The rod is lying on a table. If you want to account for gravity, there is another force that you also need to account for...SakuRERE said:
The rod is flat on the table, the weight is acting perpendicular to the table and is offset by the normal force from the table. The rod in your image is seen from above, both forces and the rod are to be considered to be in the horizontal plane. The vertical direction is therefore irrelevant.SakuRERE said:

ohh yeaah, thanks everyone. i didn't focus on that point that is layning in the table!Orodruin said:
and regarding the pivot point, i think it's the one who will decide if it will rotate or not, i mean if it was at the center of the rod than there should be not rotation, but if the pivot is not in the center (not mentioned) then the distance of each force to the pivot won't be same so then i would say there rotation. but the one answering the question didn't specify any thing !SakuRERE said:
Your reference point does not matter at all. The way you choose your reference point (which is arbitrary) cannot affect what physically happens to the rod.SakuRERE said:

thanks thanks thanks very much sirOrodruin said:
Rotation in a force and torque equation refers to the movement of an object around a fixed axis or point. It is caused by the application of a force or torque, and can be described using mathematical equations.
To solve for rotation in a force and torque equation, you need to first determine the direction and magnitude of the applied force or torque, as well as the moment of inertia and angular acceleration of the object. Then, you can use the equation: τ = Iα, where τ is the torque, I is the moment of inertia, and α is the angular acceleration.
Force and torque are both related to rotation, but they are not the same thing. Force is a push or pull on an object, while torque is a twisting force that causes rotation. In a rotation equation, force is usually represented by F and torque by τ.
Yes, you can use a force and torque equation to solve for the velocity of a rotating object, as long as you have the necessary variables such as the moment of inertia and angular acceleration. The equation used is v = ωr, where v is the linear velocity, ω is the angular velocity, and r is the distance from the axis of rotation.
Solving for rotation in a force and torque equation is important in many fields, including engineering, physics, and biomechanics. It can be used to analyze the movement of objects such as gears, wheels, and pendulums, and is crucial in designing structures and machines that need to rotate smoothly and efficiently.
