A Cable Passes Over A Pulley

A Cable Passes Over A Pulley

Where can I find angular acceleration in this problem? 3

A cable passes through the pulley. For this reason

The cable connects the pulley and the pulley is not found

z m, the tension in the cable is not so good.

Also on the opposite side of the pulley. NS

The force on one side is 122 N and the force on the other side.

The other side is 80 N.

As long as the pulley is a uniform pulley.

m 2.45 kg and radius 0.731 m

Dimensions of angular velocity.

Reply in rad / s2.

I know ± =  ”à / ” t, but I don't understand how to associate variables with this family system.

The resulting force appears 42 N in front of the weight.

T = F / r = ± * I

I = 1/2 m * r 2 for one disk

Then

 ± = (F * (1/2 * m * r 2) / r = 1/2 * F * m * r

I have 37.6 rad / s / s.

Angular velocity = torque / inertia

Torque = (125 N * 0.731 m) (80 N * 0.731 m)

Torque = 30,702 Nm

Inertia = 0.5 * m * r 2 (since it is a disk)

Inertia = 0.6546 kg.m 2

Angular velocity = 30.702 / 0.6546 = 46.9 rad / s 2
