Answer:
18 Watts
Explanation:
For this problem, we simply need to understand the relationship of power to voltage and current. This relationship is derived from Ohm's law:
Power = Voltage * Current
Given this equation, we can say the following to find the power consumption of the motor:
Power = 12volts * 1.5amps
Power = 18 Watts
Hence, the motor is consuming 18 Watts of power.

Explanation:
Engineering use a (n) Engineering design process to solve problems.
Answer:
(a) 0.1509 mm
(b) 0.00525 mm
Explanation:
Stress, 
is given by
where F is force and A is area and area is given by 
hence
where d is the diameter. Substituting 9970 N for F and 10mm=0.01 m for d hence
From the attached stress-strain diagram, the stress of 127 Mpa corresponds to strain of 0.0015 and since strain is given by
where
is the strain, 
is elongation and l is original length and making elongation the subject
and substituting strain with 0.0015 and length l with 100.6 mm then
(b)
Lateral strain is given by
and substituting 
for 
where v is poisson ratio then
and making 
the subject then
and substituting 0.35 for v, 0.0015 for strain and 10 mm for d
and the negative sign indicates decrease in diameter
Answer:
a)
b)
Explanation:
Given that
Diameter ,d= 0.15 mm
We know that pressure difference is given as
Now by putting the values
When surface tension 0.1 N/m :
The surface tension ,
When surface tension 0.12 N/m :
The surface tension ,
a)
b)
