What is the Static Equilibrium of a Pulley System?

In summary, the system in static equilibrium with a pulley, string, and mass has a tension in the string holding the pulley and a normal force on the 2.0 kg box. The 2.0 kg mass is resting on the ground and the ∑F = 0 equation for the 0.5 kg mass can be used to find the tension in the string holding the pulley.

t-(2*9.8)=F? (part a)

is the 2.0 kg mass resting on the ground?

if so, always start with the mass with the least number of forces acting on it (because that's easiest! :biggrin:), and then work your way round to the others

in this case, that's the 0.5 kg mass …

so what is the ∑F = 0 equation for that? :smile:
 

What is force question (tension)?

Force question (tension) is a term used in physics to describe the pulling force exerted by a string, cable, or other object when it is stretched. It is also known as tension force.

How is force question (tension) measured?

Force question (tension) is typically measured in units of newtons (N) using a spring scale or other force measuring instrument. It can also be calculated using the formula F = kx, where F is the force, k is the spring constant, and x is the displacement or change in length of the object.

What factors affect force question (tension)?

Force question (tension) is influenced by several factors, including the amount of force applied to the object, the stiffness of the material, and the length and cross-sectional area of the object. Changes in any of these factors can affect the amount of tension force exerted by the object.

What are some real-life examples of force question (tension)?

Force question (tension) is present in many everyday situations, such as when pulling a rope to lift an object, stretching a rubber band, or tightening the strings on a musical instrument. It is also a key factor in structures such as bridges and suspension cables.

What is the difference between force question (tension) and force question (compression)?

While both force question (tension) and force question (compression) involve the application of force to a material, they differ in the direction of the force. Force question (tension) pulls the material in opposite directions, while force question (compression) pushes it together. Additionally, force question (compression) is typically used to describe forces acting on solid objects, while force question (tension) is often used for objects with flexible components.
