A ladder leans against a wall as shown below. A hammer is placed on one of the rungs (you can assume the hammer is pointlike). The ladder feels a force of friction from the ground, but there is no friction between the ladder and the wall. (a) Choose the following values. None of them can be 0. The length of the ladder =15 m The mass of the ladder = 10kg The inclination of the ladder= 30 The height of the hammer. = 10m The mass of the hammer.= 5kg
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.
