Rod of steel, 200 mm length reduces its diameter (50 mm) by turning by 2 mm with feed speed 25 mm/min. You are required to calcu
diamong [38]

Answer:

125 cm³/min

Explanation:

The material rate of removal is usually given by the formula

Material Rate of Removal = Radial Depth of Cut * Axial Depth of Cut * Feed Rate, where

Radial Depth of Cut = 25 mm

Axial depth of cut = 200 mm

Feed rate = 25 mm/min

On multiplying all together, we will then have

MRR = 25 mm * 200 mm * 25 mm/min

MRR = 125000 mm³/min

Or we convert it to cm³/min and have

MRR = 125000 mm³/min ÷ 1000

MRR = 125 cm³/min

A freeway is being designed for a location in rolling terrain. The expected free-flow speed is 55 mi/h. During the peak hour, it
balu736 [363]

Answer:

3.

Explanation:

We start calcualting the factor for heavy-vehicle, that is,

f_{HV} = \frac{1}{1+P_T(E_T-1)+P_R(E_R-1)}

E_T = 2.5 for rolling terrain, so, replacing,

f_{HV} = \frac{1}{1+0.18(2.5-1)+0}

f_{HV} = 0.7874

We calculate the number of lanes by using the relation as follow:

N=\frac{V}{\upsilon_p PHF f_{HV} f_p}

N=\frac{2700}{1915*0.88*0.7874*1}

N= 2.035

In this way the necessary number of lanes is 3.

Note: To calculate \upsilon_p you need to consult the Exhibit 23-2

in 'Highway capacity Manual' for 55mph and the LOS D criteria.
