Problems

Machines

Solution

If the machine has a height of 5ft and the length of 7ft. what is the angle A and the length of the Hypotheses?

5x5=25

7x7=49

49+25=74

squareroot of 74

= 8.6 ft

the hypotheses is

8.6ft long.

180-90=90

90-60=30

angle A is 30

degrees.

Problems

Bolts

Solution

If Jordan is laying down tightening a bolt that's 23cm away. And wants to tighten the bolt above it that is 17 cm above. What angle does his arm have to move? and how long does his arm reach?

23x23=592

17x17=289

592+289=881

square root of

881= 29.7 is the length of his arm.

TanB: opp 17

adj 23

= Tan(90)=17/23

How Trig is Used in Mechanical Engineering

Job Description:

Mechanical Engineering

“There are three key reasons why mathematics is important for engineers: 1. The Laws of Nature (E.G., Maxwell's Equations for Electromagnetics, Kirchhoff's Rules for Circuit Analysis) are mathematical expressions. Mathematics is the language of physical science and engineering. 2. Mathematics is more than tool for solving problems; mathematics courses can develop intellectual maturity. 3. Computers do not make traditional mathematical analysis obsolete! First, computer programs contain mathematical relations; understanding these relations is still necessary. Second, debugging computer programs is a difficult art. One of the best ways to validate a program is to compare the computer simulation to the analytical solution for the same situation. Knowledge of traditional mathematical analysis is essential for this method of validating computer programs. Third, it is relatively easy to write brute-force computer code that requires a long runtime and produces significant error, owing to accumulation of errors from the limited resolution of machine numbers. Great increases in both speed and accuracy can be obtained by using analytical solutions for parts of the problem, or by careful development of appropriate algorithms.”

Mechanical engineers provide efficient solutions to the development of processes and products, ranging from small component designs to extremely large plant, machinery or vehicles. They can work on all stages of a product, from research and development to design and manufacture, through to installation and final commissioning.

Most industries rely on a form of mechanical systems and mechanical engineering is thought to be one of the most diverse of all engineering disciplines. There are employment opportunities available in a wide range of sectors, such as the manufacturing, power, construction and medical industries.

Mechanical engineers can also be involved in the management of people and resources, as well as the development and use of new materials and technologies.
