A duo-servo break makes use of mechanical arrangements to multiply the braking force
The technician that gives the correct procedure of reassembly of duo-servo brake is Tech B, therefore;
Tech B only is correct
The process by which the above answer is arrived at
To reassemble a duo-servo brake, the first step is to reassemble on the brake shoe and parking brake cable, the parking brake lever. The star wheel assembly is then reassembled, and set aside after lubricating the floating end. The pads on the backing plate are lubricated and both brake shoes are then installed on the backing plate
Therefore, Tech A states that the brake shoes on the backing plate are reassembled first is not correct, while Tech B is correct

Answer:
ω=314.15 rad/s.
0.02 s.
Explanation:
Given that
Motor speed ,N= 3000 revolutions per minute
N= 3000 RPM
The speed of the motor in rad/s given as
Now by putting the values in the above equation
ω=314.15 rad/s
Therefore the speed in rad/s will be 314.15 rad/s.
The speed in rev/sec given as
ω= 50 rev/s
It take 1 sec to cover 50 revolutions
That is why to cover 1 revolution it take
Answer:
The correct option is;
Fluid power systems are much more efficient with regards to energy costs and overall cost savings
Explanation:
The option that will provide a valid reason for the larger proportion of the consumers to change to the fluid power trucks from the diesel powered trucks is the possibility of increased efficiency in the cost of energy, and the cost savings to be made from making the switch to the fluid power trucks, due to the lower input required and the faster rate at which the consumer budget will be rebalanced leading to increased return on investment and improved rate of return.
Answer:
The external pressure is p = -21.9 psf or p = -8.85 psf
Explanation:
Given :
Velocity of wind, v = 120 mi / hr
(wind direction factor)
= topographical factor (for flat terrain)
= velocity pressure at height h
But for height h = 30 ft, 
= 0.98 (from table)
= 36.16
Now, 
, so 
(from table)
where, p = external pressure
G = 0.85 = gust factor (for typical rigid building)
(internal pressure co efficient)
Therefore putting the values,
p = -21.9 psf or p = -8.85 psf
