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
