Answer:
A periodic function is a function that returns to its value over a certain period at regular intervals an example is the wave form of flux density (B) = sin <em>wt</em>
Explanation:
A periodic function is a function that returns to its value over a certain period at regular intervals an example is the wave form of flux density (B) = sin <em>wt</em>
attached to the answer is a free plot of the output starting with zero degree for one coil rotating in a uniform magnetic field
B ( wave flux density ) = Bm sin<em>wt and w = </em>2f = rad/sec
Answer:
Value of Young's modulus is obtained as
Explanation:
We know from the basic stress strain relationship
Stress is obtained as
now the strain is obtained as
using these values in the above equation we obtain E as
Answer:
they all use scientific knowledge to solve a problem
Explanation:
Engineers are professional who make use of the scientific technique or knowledge to provide a solution to the problems of the society.
They are well qualified to provide solutions or make some projects or products which makes life easier.
There are various engineers belonging to the various fields and sectors. They are the civil engineers who give expertise mainly in the construction sector making multi story buildings, bridges using their scientific knowledge, there are mechanical engineers who build various engines to make life easier using mathematical tools and scientific techniques, then there are electrical engineers who basically provide solutions to the electrical sectors, chemical engineers use their knowledge to help people and the society to build and design the fuels, foods, chemicals, pharmaceuticals,etc.
