Answer:
324.3Nm
Explanation:
The torque is given by the equation

in this case the vectors r and F are perpendicular between them, thus:

The forces acting on the mass are:
(1)
where T is the tension of the cable, M is the mass and a is the acceleration.
Furthermore, we have that the acceleration is:

By replacing in (1) we can obtain:

The force T produces the torque on the pulley, hence:

the answer is 324.4Nm
hope this helps!
Answer:
0.08821 kgm²
Explanation:
f = Frequency = 1.7 Hz
m = Mass of lower leg = 5.7 kg
d = Distance of center of mass = 18 cm
g = Acceleration due to gravity = 9.81 m/s²
I = Moment of inertia
Frequency is given by

The moment of inertia of the lower leg is 0.08821 kgm²
Answer:
The role of a commutator in a electric generator is a rotary switch (in certain types of electrical generators that periodically reverse the current direction between the rotor and the external circuit by that reversing it in the current direction teb rotating windings all half turn a force called torque is produced)
