What happens after ultimate tensile strength? However, once the tensile strength is exceeded, the test specimen begins to thin down, or neck, at some location along the length. All of the rest of the deformation to failure occurs at this point as the stress is concentrated in this area of reduced cross section. Why does […]

Why did we stop using steam engines?
Why did we stop using steam engines? According to the designers, diesel engines could run faster and work longer than steam locomotives. They used a vast amount of energy to build up steam pressure, which had to be discarded whenever the locomotive stopped or shut down. In every week of operation, a locomotive consumed its […]

What are the advantages of closed loop system?
What are the advantages of closed loop system? Closed loop control systems are more accurate even in the presence of non-linearities. The sensitivity of the system may be made small to make the system more stable. The closed loop systems are less affected by noise. What is an example of a closed loop system? Two […]
How do you find the critical points of a function?
How do you find the critical points of a function? A critical point occurs when the derivative is 0 or undefined. If our equation is f(x)=mx+b, we get f'(x)=m. So if the function is constant (m=0) we get infinitely many critical points. How do you find the function of two variables? First, take the partial […]
