Static Equilibrium The uniform seesaw shown below is balanced on a fulcrum located 4.00 m from the left end (shown as x, on the picture). The fulcrum is a distance of 5.00 m from the right side (shown on the picture as x₂). The boy on the right has a mass of 35.0 kg and the boy on the left has a mass 70.0 kg. They managed to have a system that is not moving- it is in equilibrium. But the boys are not touching the ground with their feet- it is just the forces and uneven fulcrum that keeps it balanced. What is the mass of the seesaw? X₁+ A X₂

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.

Question

Static Equilibrium
The uniform seesaw shown below is balanced on a fulcrum located 4.00 m from the left end (shown as x, on the picture). The fulcrum
is a distance of 5.00 m from the right side (shown on the picture as x₂).
The boy on the right has a mass of 35.0 kg and the boy on the left has a mass 70.0 kg. They managed to have a system that is not
moving - it is in equilibrium. But the boys are not touching the ground with their feet- it is just the forces and uneven fulcrum that
keeps it balanced.

1. The figure below shows the normal configuration of the head with proper posture. The center of mass for the weight of the skull is labeled W and the muscles that attach to the back of the skull are labeled M. Assume all quantities are correct to 2 significant figures. M W a) Determine the mechanical advantage of the skull muscles when d₁ 20 mm and d₂ = 26 mm. Hint: Which force on the fulcrum (rotation point) is the effort, and which is the load? Enter to 2 significant figures Mechanical Advantage: b) Improper posture and positioning of the head can lead to muscle tension headaches. If the head begins to shift forward while studying or reading, the center of mass moves further from the fulcrum or pivot point. It is a subtle change, but the figure below shows the head shifted forward.

A balance has a 5.0kg object at 0.5m from the fulcrum, and a 20.0kg object a certain ways in the opposite direction from the fulcrum. Where would the 20.0kg object need to be for the system to be balanced? Suppose you placed the 20.0kg object at 0.5m away from the fulcrum in the opposite direction of the 5.0kg object. This would result in an unbalanced system. Where could you then place a 10kg object to rebalance the system?
