No clue sorry man I would help but I need help too
Answer:
3 industries that often need the skills of mechanical engineers are:
The key skills mechanical engineers bring to these industries are effective technical skills, the ability to work under pressure, problem-solving skills, creativity and teamwork.
Explanation:
Automotive industry: The skills mechanical engineers bring to automotive industry include designing new cars for development, conducting laboratory testing for performance safety, and troubleshooting design or manufacturing issues with recalled vehicles. Automotive engineers have:
- good mathematical skills, for instance in calculating the stresses power trains and other parts have to withstand;
- understanding and application of principles of physics and chemistry to properly design engines, electrical systems and other car components;
- good computer skills, because 21st century engineers rely on computer-assisted design software;
- knowledge of ergonomics, which is applied in the process of designing a car so that the driver and passengers have a comfortable and functional environment, is another skill mechanical; engineers need.
Construction industry: Mechanical engineers are responsible for designing, building, establishing, and maintaining all kinds of mechanical machinery, tools, and components in the construction industry.
Aerospace industry: Mechanical engineers in aerospace industry produce specifications for design, development, manufacture and installing of new or modified mechanical components or systems. They design more fuel-efficient aircraft that cut emissions and build the fleets of satellites that power modern GPS technology.
Answer:
In C++:
#include <iostream>
#include <cmath>
using namespace std;
int main(){
double total = 0;
for(int i = -170; i<=-130;i++){
if(i%2 == 0 && i%7==0){
double angle = i*3.14159/180;
total+=sin(angle); } }
cout<<"Total: "<<total;
return 0;
}
Explanation:
This initializes the total to 0
double total = 0;
This iterates from -170 to - 130
for(int i = -170; i<=-130;i++){
This checks if the current number is even and is divided by 7
if(i%2 == 0 && i%7==0){
This converts the number from degrees to radians
double angle = i*3.14159/180;
This adds the sine of the number
total+=sin(angle); } }
This prints the calculated total
cout<<"Total: "<<total;
Answer:
M_o = 18.84 N*m in the clockwise direction.
Explanation:
Given:
- Force F = 120 N
- base b = 610 mm
- height h = 330 mm
Find:
Moment M_o about origin and its direction:
Solution:
- The force has two components F_x and F_y along base b and height h, respectively:
F_x = F*cos(Q)
F_x = F*(h / sqrt (h^2 + b^2))
F_x = 120*(330 / sqrt (330^2 + 610^2))
F_x = 57.098 N
- We can skip F_y as it passes through the the origin, hence moment produced is zero.
- Moment about O is :
M_o = F_x * h
M_o = 57.098*.33
M_o = 18.84 N*m in the clockwise direction.
