Answer:
Time constant of RC circuit is 0.105 seconds.
Explanation:
It is given that,
Resistance,
Capacitance,
We need to find the expected time constant for this RC circuit. It can be calculated as :
So, the time constant for this RC circuit is 0.105 seconds. Hence, this is the required solution.
Answer:
P=740 KPa
Δ=7.4 mm
Explanation:
Given that
Diameter of plunger,d=30 mm
Diameter of sleeve ,D=32 mm
Length .L=50 mm
E= 5 MPa
n=0.45
As we know that
Lateral strain
We know that
So the axial pressure
P=740 KPa
The movement in the sleeve
Δ=7.4 mm
