Answer:
While calculating the stresses in a body since we we assume a constant distribution of stress across a cross section if the body is loaded along the centroid of the cross section , this assumption of uniformity is assumed only on the basis of Saint Venant's Principle.
Saint venant principle states that the non uniformity in the stress at the point of application of load is only significant at small distances below the load and depths greater than the width of the loaded material this non uniformity is negligible and hence a uniform stress distribution is a reasonable and correct assumption while solving the body for stresses thus greatly simplifying the analysis.
Parallel Resistor Equation
If the two resistances or impedances in parallel are equal and of the same value, then the total or equivalent resistance, RT is equal to half the value of one resistor. That is equal to R/2 and for three equal resistors in parallel, R/3, etc.
Answer and Explanation:
The criteria defined for the instruments that changes rapidly with time, ae called dynamic characteristics. These characteristics are namely
1. Speed of response
2. Fidelity
3. Dynamic error
4. Measuring lag
Speed of response
It is the speed with which a measurement system responds to changes in the measured quantity.
Fidelity
It is the degree to which a measurement system indicates changes in the measured quantity without dynamic error.
Dynamic error
It is the difference between the true value of the quantity changing with time and the value indicated by the measurement system if no static error is assumed. It is also known as measurement error.
Measuring lag
It is the delay in the response of a measurement system to changes in the measured quantity. It is divided into two as follows.
