Answer:

Option B

Lockout/ Tagout

Explanation:

lockout and tagout is a safety procedure used in most industries and work places. This ensures that during any maintenance work, that dangerous machines are properly shut off and not able to be started up again prior to the completion of maintenance or repair work.

The procedure includes:

1. Turns off and disconnects the machinery or equipment from its energy source(s) before performing service or maintenance.

2. The authorized employee(s) either lock or tag the energy-isolating device(s) to prevent the release of hazardous energy.

In a mechanical assembly operation, the first work unit required 7.83 min to complete and the learning rate for mechanical assem
Marianna [84]

Answer:

(a) 6.5774 minutes

(b) 4.3879 minutes

(c) 2.459 minutes

(d) 245.902 minutes

Explanation:

The learning curve model follows the following equation:

Y=aX^b

where Y are the units time to produce X units, and a is the time for assembly the first unit. Additionally, b is calculated as:

b=\frac{ln(r)}{ln(2)}

Where r is the learning rate for mechanical assembly. So, b is equal to:

b=\frac{ln(0.84)}{ln(2)}=-0.2515

Then, the equation is:

Y=7.83X^{-0.2515}

Finally, the unit times to produce the second unit are:

Y=7.83(2)^{-0.2515}=6.5774

The 10th unit:

Y=7.83(10)^{-0.2515}=4.3879

The 100th unit:

Y=7.83(100)^{-0.2515}=2.459

Then, the total cumulative time T to produce 100 units in the Crawford model is calculated as:

T=7.83\frac{(100.5)^{1-0.2515}-(0.5)^{1-0.2515})}{1-0.2515} \\T=323.5383

An equal-tangent vertical curve is to be constructed between grades of -2% (initial) and 1% (final). The PVI is at station 110 0
Mila [183]

Answer:

The curve length (<em>L</em>) will be = 1218 ft

The elevations and stations for PVC and PVI

a. station of PVC = 103 + 91.00

b. station of PVI = 116 + 09.00

c. elevation of PVC = 432.18ft

d. elevation of PVI = 426.09ft

Explanation:

First calculate for the length (<em>L</em>)

To calculate the length, use the formula of "elevation at any point".

where, elevation at any point = 424.5.

and ∴ PVC Elevation = (420 + 0.01L)

Then, calculate for Station of PVC and PVI and elevation of PVC and PVI
