Test: Moment Area Theorems - 1 - Question 1

### θB/A refers to:-

Detailed Solution for Test: Moment Area Theorems - 1 - Question 1

Explanation: In the above given equation, if A is first point and B is second, then θB/A is the LHS.

Test: Moment Area Theorems - 1 - Question 2

### If area of M/EI diagram between points A and B is –ve, then angle from tangent A to tangent B will be measured :-

Detailed Solution for Test: Moment Area Theorems - 1 - Question 2

Explanation: Standard sign convention is applied everywhere in the proof, so it is quite obvious.

Test: Moment Area Theorems - 1 - Question 3

### What is the dimension of θB/A if area is measured in SI unit:-

Detailed Solution for Test: Moment Area Theorems - 1 - Question 3

Explanation: Since area is measured in SI units, result too will be in Si units.

Test: Moment Area Theorems - 1 - Question 4

The vertical deviation is measured along (if first point is A and second point is B):-

Detailed Solution for Test: Moment Area Theorems - 1 - Question 4

This makes the integration much easier during calculation of deflection.

Test: Moment Area Theorems - 1 - Question 5

he vertical deviation of tangent at point say A on the elastic curve with respect to the tangent extended from another point say B equals the “moment” of the area under the M/EI diagram between the two points about point :-

Detailed Solution for Test: Moment Area Theorems - 1 - Question 5

Explanation: Since, we are taking A as origin.

Test: Moment Area Theorems - 1 - Question 6

–ve M/EI area means tangent at A is:-

Detailed Solution for Test: Moment Area Theorems - 1 - Question 6

Explanation: Since, during derivation we have always assumed upward to be positive.

Test: Moment Area Theorems - 1 - Question 7

In general tA/B implies:-

Detailed Solution for Test: Moment Area Theorems - 1 - Question 7

Explanation: It is just a standard to differentiate between tA/B and tB/A.

Test: Moment Area Theorems - 1 - Question 8

TA/B and tB/A are:-

Detailed Solution for Test: Moment Area Theorems - 1 - Question 8

Explanation: In one case, we will take moment about point A while in other case moment is taken about point B. So, it can be anything.

Test: Moment Area Theorems - 1 - Question 9

The change in slope between any two points on the elastic curve equals the area of M/EI diagram between both end points of beam.
State whether the above statement is true or false.

Detailed Solution for Test: Moment Area Theorems - 1 - Question 9

Explanation: Change in slope will be equal to area of M/EI diagram between those two points.

Test: Moment Area Theorems - 1 - Question 10

–ve moment bends the beam convex down.
State whether the above sentence is true or false.
