I couldn't find in the attachment where the units of mass are stated. I assume they are kg. So you have a 2kg mass attached at 20cm from the fulcrum. g is given as 9.8m/s2. Paying careful attention to units, what does that give for the torque?Yoli123 said:
Equilibrium in a rotation lab refers to a state where an object is not rotating or accelerating. This means that the net torque acting on the object is zero, and the object is either at rest or moving at a constant angular velocity.
Equilibrium is achieved in a rotation lab by balancing the forces acting on an object. This can be done by adjusting the position of weights or changing the angle of the object. The goal is to create a state where the net torque is zero.
The purpose of studying equilibrium in a rotation lab is to understand the principles of rotational motion and how forces and torques act on objects. This knowledge is important in various fields such as engineering, physics, and mechanics.
The net torque in a rotation lab can be calculated by multiplying the force applied to an object by the distance from the pivot point. This can be represented by the equation Στ = F x d, where Στ is the net torque, F is the force, and d is the distance from the pivot point.
Equilibrium in a rotation lab has many real-life applications, such as designing stable structures, analyzing the forces acting on a rotating object, and understanding the balance of forces in machines and vehicles. It is also important in sports, such as gymnastics and figure skating, where maintaining balance and control is crucial.
