Answer:

*True*

Explanation:

Today's concrete is made using Portland cement, coarse and fine aggregates of stone and sand, and water. However, cement is not concrete. Concrete is a composite building material and the ingredients, of which cement is just one, have changed over time and are changing even now.

rewona [7]

If a clock frequency is applied to a cascaded counter, The lowest output frequency available will be

The lowest output frequency will be = $2.5kHz$

<h3>Cascade Counter</h3>

For a cascade counter,

Overall frequency = $5*8*10*10$

Overall frequency = $4000$

<h3>Lowest Frequency</h3>

Therefore,

the lowest frequency

$F = \frac{10*10^6}{4*10^3}\\\\F = 2500Hz\\\\F = 2.5kHz$

The steel bracket is used to connect the ends of two cables. if the allowable normal stress for the steel is sallow = 30 ksi, de

The largest tensile force that can be applied to the cables given a rod with diameter 1.5 is 2013.15lb

<h3>The static equilibrium is given as:</h3>

F = P (Normal force)

Formula for moment at section

M = P(4 + 1.5/2)

= 4.75p

Solve for the cross sectional area

Area = $\frac{\pi d^{2} }{4}$

d = 1.5

$\frac{\pi *1.5^{2} }{4}$

= 1.767 inches²

<h3>Solve for inertia</h3>

$\frac{\pi *0.75^4}{4}$

= 0.2485inches⁴

Solve for the tensile force from here

$\frac{F}{A} +\frac{Mc}{I}$

30x10³ = $\frac{P}{1.767} +\frac{4.75p*0.75}{0.2485} \\\\$

30000 = 14.902 p

divide through by 14.902

2013.15 = P

The largest tensile force that can be applied to the cables given a rod with diameter 1.5 is 2013.15lb
