There are many types of structural elements. It was seen in an earlier lecture that the support condition has a significant influence on the behavior of the specific element. It is advantagous to identify certain types of structural elements which have distinct characteristics. If an element has pins or hinge supports at both ends and carries no load in-between, it is called a two-force member.
Energy stored in a capacitor is Electric Potential Energy. Capacitor is device used for storing energy. The work done to charge is a capacitor is stored in it in the form of Electrical potential energy. Electrical potential energy is defined as capacity to do work due to the position change. For example, we know fans have capacitor installed in it. When we turn off the fan, it continue moving using the electrical energy stored in the capacitor.
Answer:
65 Hz, 95 Hz, 150 Hz, 180 Hz, 310 Hz, 340 Hz
Explanation:
Given :
Frequencies of the sinusoids,
, and
Sampling rate
The positive frequencies at the output of the sampling system are :
When n = 0,
when n = 1,
When n = 2,
Therefore, the first six positive frequencies present in the replicated spectrum are :
65 Hz, 95 Hz, 150 Hz, 180 Hz, 310 Hz, 340 Hz
Answer

Answer:
The minimum power neccesary is:
Explanation:
The water is bring to a boil so it goes from 25°C to 100°C, the temperature rise si:
Considering that the cup is always at the same temperatura as the water the trasfered energy can be calculated as:
We have that:
So:
Given that this energy was supplied in 2 minutes:
The minimum power neccesary is:
