Test: Idealized Structure - Question 1

### How many constraints are there in a fixed support?

Detailed Solution for Test: Idealized Structure - Question 1

Explanation: It is not mentioned in the question that whether the fixed support is used in planar system (3 constraints) or in 3D system (6 constraints).

Test: Idealized Structure - Question 2

### How many constraints are there in a free-rotation support used in a planar system?

Detailed Solution for Test: Idealized Structure - Question 2

Explanation: There are 2 constraints, reaction in x and y direction. Rotation is allowed as the name implies.

Test: Idealized Structure - Question 3

### If we use a link support in a structural system, then how many unknowns would we have?

Detailed Solution for Test: Idealized Structure - Question 3

Explanation: There will always be only 1 unknown if link support is used and that is the force acting along the axis of the link.

Test: Idealized Structure - Question 4

Moment at a hinge will be:-

Detailed Solution for Test: Idealized Structure - Question 4

Explanation: Only shear forces act in the case of hinge.

Test: Idealized Structure - Question 5

Concrete is:-

Detailed Solution for Test: Idealized Structure - Question 5

Explanation: Concrete consists of aggregates and they are good in carrying compression. But, during tension joint between cement and aggregate cracks resulting in inefficiency.

Test: Idealized Structure - Question 6

Why are steel reinforcing rods used in concrete beams:-

Detailed Solution for Test: Idealized Structure - Question 6

Explanation: Concrete is weak in carrying tension, but is good in compression.

Test: Idealized Structure - Question 7

A surface structure has:-

Detailed Solution for Test: Idealized Structure - Question 7

Explanation: They support very little bending. So, to minmize I(flexural rigidity), thickness is small.

Test: Idealized Structure - Question 8

For instability, at least one joint of the structure should be able to displace without causing change in length of all the members.
State whether the above statement is true or false.
