Rotational Equilibrium And Rotational Dynamics

In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.

Equilibrium of Forces

The tension created on one body during push or pull is known as force.

Consider an unsuccessful attempt to take off a tire using a wrench to loosen the bolts. Assume the wrench is 0.3m long and are you able to apply a 200N force Because the tire is flat you can only apply your force at a 60° angle. What is the torque at the center of the bolt. You find a tire jack and are now able to apply 200N of force at an 80° angle. Is the resulting torque more or less and what is the new torque.

τ=rFsinθIs the version of torque we should now be using A ladder with a length of 2m and a mass of 5kg is resting against a wall so that it makes an angle of 60 degrees with the floor as shown above. Assuming that the mass of the ladder is distributed uniformly, what is the torque due to the weight of the ladder about its base? Remember, torque on an object will cause it to rotate if possible, even if the ladder is not rotating about the base (pivot point) the weight of the ladder would still cause it to rotate if the wall were to disappear. Hint: the angle should be between the FORCE and the RADIUS. Answer to 2 decimal places if possible
