How does mass of pulley affect acceleration?

The larger the mass of the pulley the less the acceleration of the object. If you know the the mass and moment of inertia of the pulley then you can calculate the acceleration. Note that for the most common pulley shapes (e.g. disc, hoop and disc, mostly hoop), the acceleration will be independent of the radius.

How do you find the acceleration of a pulley?

Calculate the force caused by gravity on the basic pulley system using the following equation: G(1) = M(1) x n and G(2) = M(2) x n. The gravitational acceleration n is a constant equal to 9.8 m/s².

What happens when the pulley has mass?

Because the pulley possesses mass, you need to apply a non-zero net torque to it to increase its angular acceleration (assuming that is the goal here). If the tensions were the same on both sides of the contact point between the string and the pulley, there would be no angular acceleration.

Does the mass of the pulley affect torque?

Physical picture: In the Atwood’s machine, the tension force pulling on the heavier mass M is larger than that pulling on the lighter mass m. This results in a net clockwise torque and hence a clockwise angular acceleration in the pulley.

How do you find acceleration with mass and tension?

mass x acceleration = tension – weight For a mass m= kg, the rope must support its weight = mg = Newtons to hold it up at rest. If the acceleration is a= m/s2 then a net force= Newtons is required to accelerate the mass. This requires a tension of T= Newtons.

What is acceleration of pulley?

Acceleration = m/s² With this acceleration, the tension in the rope will be. T= Newtons compared to the weight W = Newtons for the hanging mass. If the weight of the hanging mass is less than the frictional resistance force acting on the mass on the table, then the acceleration will be zero.

Does a pulley with mass affect tension?

Mass-less pulley is characterized by the fact that it does not affect the magnitude of tension in the string. It means that tensions in the string on either side of the pulley remains same. In general, a “mass-less” pulley changes the direction of force (tension) without any change in magnitude.
