Answer and Explanation:
Commutator are used in DC machine commutator is mainly used for the reversing the direction of the current .It is connected to the armature of the DC generator or motor
ADVANTAGE OF COMMUTATOR The main advantage of the commutator in DC motor is to keep keep the direction of the toque always in the same direction by changing the current direction
DISADVANTAGE OF COMMUTATOR : The main disadvantage is due to the friction between the commutator and brushes there is a friction loss.
Answer:
A working with machinery be a common type of caught-in and caught-between hazard is described below in complete detail.
Explanation:
“Caught in-between” accidents kill mechanics in a variety of techniques. These incorporate cave-ins and other hazards of tunneling activity; body parts extracted into unconscious machinery; reaching within the swing range of cranes and other installation material; caught between machine & fixed objects.
Answer:
hello your question is incomplete attached below is the complete question
answer : attached below
Explanation:
let ; x(t) be a real value signal for x ( jw ) = 0 , |w| > 200![\pi](https://tex.z-dn.net/?f=%5Cpi)
g(t) = x ( t ) sin ( 2000 ![\pi t )](https://tex.z-dn.net/?f=%5Cpi%20t%20%29)
![x_{1} (t) = \frac{1}{2} x(t) sin ( 4000\pi t )](https://tex.z-dn.net/?f=x_%7B1%7D%20%28t%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%20x%28t%29%20%20sin%20%28%204000%5Cpi%20t%20%29)
next we apply Fourier transform
attached below is the remaining part of the solution
