Answer: 0.025 in = 0.065 mm
Explanation: To convert the value in inches to mm we have to multiply the inches by the conversion factor 25.4.
So, 0.025 × 25.4 = 0.065 mm (millimeter)
Conversion formula for calculation in (inch) into mm is:
Value in mm = Value in in × 25.4
- One inch is equal to the 25.4 mm.
Answer:
The minimum value of wall thickness t=3.63 mm.
Explanation:
Given:
D=200 mm
P=4 MPa
t= Wall thickness
maximum shear stress=27.5 MPa
We know that
hoop stress 
Longitudinal stress 
So maximum shear tress in plane
Now by putting the value
So t=3.36 mm
The minimum value of wall thickness t=3.63 mm.
Answer:
Explanation:
From the question we are told that:
Plane strain fracture toughness of 
Y value 
Stress level of
Generally the equation for length of a surface crack is mathematically given by
Therefore
in mm
Answer:
b. Technician B only
Explanation:
A watchdog timer is a circuit that automatically monitors the MCU (Microcontroller Unit) for any anomaly, detects it and helps the MCU to recover from the malfunction it has detected.
If the input signal turn-on time is too fast for the input circuit, that is a malfunction and this activates the watchdog timer circuit to correct this malfunction immediately. So Technician B only is correct as the watchdog timer is activated immediately once there is a malfunction.
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.
