What form of joining uses heat to create coalescence of the materials?

Write a function called pyramid(height) that acceptsa parameter ""height"". It then prints a pyramid of that height

vichka [17]

Answer:

I am writing a function in C++

Explanation:

<h2>C++ program</h2>

#include <iostream>

using namespace std;

int pyramid(int height) // function pyramid with parameter height

{int distance; //variable for spaces

for(int i = 1, j = 0; i <= height; ++i, j= 0) //handle the rows

{

for(distance= 1; distance<= height-i; ++distance)

// handles the spaces & columns

{ cout <<" "; } //prints spaces between stars

while(j!= 2*i-1) //handles shape and spaces

{ cout << "* "; // printing stars

++j; }

cout << '\n'; } } // for the next line

int main()

{

int height; //declare height variable

cout <<"Enter height of pyramid "; //asks user to enter height of pyramid

cin>>height; //stores value of height

pyramid(height); //calls pyramid function

}

Why is a crank-rocker mechanism more useful than a double-rocker mechanism?

klasskru [66]

Answer:

explained

Explanation:

Crank rocker mechanism is formed when the shorter link revolves and the others rock( oscilllates)

Whereas the double rocker mechanism is formed when both the side link rock and the others oscillate.

Crank rocker mechanism can be used to convert rotary motion into oscillatory motion.

What have you learned about designing solutions? How does this apply to engineering? Think of some engineering solutions that st

Andrew [12]

Answer:

In engineering design, failure is expected. It helps you find the best solutions before implementing them in the “real world”. Having a prototype fail is a GOOD thing, because that means you have learned something new about the problem and potential solutions.

The idling engines of a landing turbojet produce forward thrust when operating in a normal manner, but they can produce reverse

sertanlavr [38]

Answer:

T = 5416.67 N

T = -2083.5 N

T = 0

Explanation:

Forward thrust has positive values and reverse thrust has negative values.

part a

Flight speed u = ( 150 km / h ) / 3.6 = 41.67 km / s

The thrust force represents the horizontal or x-component of momentum equation:

$T = flow(m_{exhaust})*(u_{exhaust} - u_{flight} )\\T = (50 kg/s ) * (150 - 41.67)\\\\T = 5416.67 N$

Answer: The thrust force T = 5416.67 N

part b

Now the exhaust velocity is now vertical due to reverse thrust application, then it has a zero horizontal component, thus thrust equation is:

$T = flow(m_{exhaust})*(u_{exhaust} - u_{flight} )\\T = (50 kg/s ) * (0 - 41.67)\\\\T = -2083.5 N$

Answer: The thrust force T = -2083.5 N reverse direction

part c

Now the exhaust velocity and flight velocity is zero, then it has a zero horizontal component, thus thrust is also zero as there is no difference in two velocities in x direction.

Answer: T = 0 N
