The 10 foot wide circle quarter gate AB is articulated at A. Determine the contact force between the gate and the smooth surface

slamgirl [31]

Answer:

$F = 641,771.52 \dfrac{lb-ft}{s^2}$

Explanation:

Given that

R=8 ft

Width= 10 ft

We know that hydro statics force given as

F=ρ g A X

ρ is the density of fluid

A projected area on vertical plane

X is distance of center mass of projected plane from free surface of water.

Here

X=8/2 ⇒X=4 ft

A=8 x 10=80 $ft^2$

So now putting the values

F=ρ g A X

F=62.4(32.14)(80)(4)

$F = 641,771.52 \dfrac{lb-ft}{s^2}$

Consider a N-channel enhancement MOSFET with VGS = 3V, Vt = 1 V, VDS = 10 V, and lambda =0 (channel length modulation parameter)

AveGali [126]

The current IDS is greater than 0 since the VGS has induced an inversion layer and the transistor is operating in the saturation region.

<u>Explanation:</u>

Since $V_{ds}$ > $V_{gs} - Vt$ because $V_{gs}$ > Vt.
By the saturation region the MOSFET is operating.
A specific source voltage and gate of NMOS, the voltage get drained during the specific level, the drain voltage is rises beyond where there is no effect of current during saturated region.
MOSFET is a transistor which is a device of semiconductor vastly used for the electronic amplifying signals and switching in the devices of electronics.
The core of this is integrated circuit.
It is fabricated and designed in an individual chips due to tiny sizes.

Calculate the link parameter and channel utilization efficiency (in error-free channels) for a system with the following paramet

larisa86 [58]

Answer: a) 0.77 and 0.39 b) 3.9 and 0.20

Explanation:

We have to find two things here i.e link parameter and channel utilization efficiency.

We are given

Bitrate= 12 Mbps,

Distance= 6 miles

Propagation Velocity= 3 x 10⁸ m/s

Length of frame= 500 bits

We know that The link parameter is related to propagation time and frame time

Where Propagation time= Bitrate x Distance= 12 Mbps x 6 miles

and Frame time= Propagation velocity x length of frame= 3 x 10⁸ x 500

So,

Link parameter= $\frac{12*10^6*6*1609.34}{3*10^8*500}$

Link parameter= 0.77

Channel utilization efficiency= $\frac{1}{1+2* link parameter}$

Channel utilization efficiency= 0.39

We are given

Bitrate= 10 Mbps,

Distance= 15 km

Propagation Velocity= 3 x 10⁸ m/s

Length of frame= 256 bits

We know that The link parameter is related to propagation time and frame time, Here QPSK is used so bitrate is multiplied by 2,

Where Propagation time= Bitrate x Distance= 2 x 10 Mbps x 15 km

and Frame time= Propagation velocity x length of frame= 3 x 10⁸ x 256

So,

Link parameter= $\frac{2*10*10^6*15*1000}{3*10^8*256}$

Link parameter= 3.9

Channel utilization efficiency= $\frac{1}{1+2* link parameter}$

Channel utilization efficiency= 0.20

B. Is the "Loading Time" of any online application a functional or a non-functional requirement? Can the requirement engineers s

Evgen [1.6K]

Answer:

Non functional

Explanation:

Loading time is a requirement that does not work in applications. There are many non-functional requirements, such as the usability, performance, and reliability of the application. The loading time falls into the display category.
Generally, the loading time limit is specified in the application, and the application is exempt from the application for exit if the application loading time is too long
