Answer:

93.8 sec

Explanation:

it is given that tab has 350 gallon

we know that 1 gallon = 0.134 cubic foot

350 gallon = 350×0.134=46.9 cubic foot

the delivery pressure is 100 psi which is greater than 80 psi to operate machine

it is given that supply volume is 30 cubic foot per minute

=   \frac{30}{60}=0.5 ft^{3}/sec

time\ required\ =\frac{tab\ air }{supply\ volume}

time\ required\=  [tex]\frac{46.9}{0.5}

=93.8 sec

A 65-tooth spur gear is in mesh with a 32-tooth pinion. For a diametral pitch equal to 7 and pressure angle equal to 20 degrees.
alex41 [277]

Answer:

0.4488 mm

Explanation:

Number of teeth in spur gear = 65

Number of teeth in pinion = 32

Diametral pitch = 7 = P

pressure angle = ∅ = 20°

Circular pitch of measured on the pitch circle is defined as the distance between two corresponding points.

Circular pitch

p=\frac{\pi}{P}\\\Rightarrow p=\frac{\pi}{7}\\\Rightarrow p=0.4488\ mm

So, the circular pitch is 0.4488 mm

A solenoid with a length of 20 cm and a radius of 5 cm consists of 400 turns and carries a current of 12 A. If z = 0 represents
forsale [732]

Answer:

Copy MATLAB code to plot the magnitude of magnetic field strength with respect to z on the axis of solenoid:

z=-20:0.01:20;

H=120.*(((20-(2.*z))./sqrt((20-(2.*z)).^2+100))+((20+(2.*z))./sqrt((20+(2.*z)).^2+100)));

plot(z,H)

title('plot of |H| vs z along the axis of solenoid')

ylabel('Magnitude of magnetic field 'H")

xlabel('position on axis of solenoid 'z")

Explanation:

full explanation is attached as picture and the resultant plot also.
