A motor gives pulley A an angular acceleration αA = (2 t3) rad / s2, where t is in seconds. If you are initially rotating at an angular speed ωA = 15 rad / s, determine the speed and acceleration of point D when t = 3 s. Point D is on pulley C. Pulley B is fixed to pulley C and rotates together. Un motor le da a la polea A una aceleración angular QA = ( 2 t)...

In the figure, two 6.20 kg blocks are connected by a massless string over a pulley of radius 2.40 cm and rotational inertia of 7.40 Times 10^-1 kg m^2. The string does not slip on the pulley; and there is no friction between the table and the sliding block; the pulley's axis is frictionless. When this system is released from rest the pulley turns through 1.30 rad in 91.0 ms and the acceleration of the blocks is constant. What are...

Use energy considerations to derive an expression for the angular acceleration of the pulley of moment of inertia I in the figure below. Assume the friction between the pulley and its axle are negligible. Also assume that the friction between the masses and the surfaces is negligible.
If the pulley is being held by a force sensor, assuming pulley and string are massless, the force would measure the combination of tension in both sides of the rope. Assume that you are lightly holding the string on top of the pulley to prevent movement. (Your finger doesn't add weight, it just holds the string still). How does the force measured change from this moment (string held still) to when the system is able to freely accelerate? Explain why.
