1. Calculate kinematic indeterminacy of following pin jointed plane frame.

$Calculate kinematic indeterminacy of following pin jointed plane frame.\r\n \r\n$

4 5 6 8

4

The truss is supported by hinged support at both ends. Hinged support in a pin jointed plane frame does not offers any degree of freedom as rotation is not considered. For given truss, it consists of two pin joint offering two degree of freedom each. Therefore, degree of freedom is 4.

Hint Answer

2. What is kinematic indeterminacy for given figure considering axial deformation?

$What is kinematic indeterminacy for given figure considering axial deformation?\r\n\r\n$

0 4 6 10

0

The given beam is supported by fixed support at both of it ends. Fixed support, if not considering axial deformation does not any degree of freedom. Therefore, degree of freedom of beam is 0.

Hint Answer

3. How many possible set of forces does a statically determinate truss has?

0 1 2 3

1

A statically determinate truss has only one set of solution set called unique solution.

Hint Answer

4. The degree of freedom for a pin jointed space frame is given by ____

2j – r 3j – r 3j – m – r 6j – r

3j – r

The degree of freedom for a pin jointed space frame is given by 3j ? r, where j is number of joints and r is number of reactions.

Hint Answer

5. Why is base plate provided in short roof trusses?

To transmit load effectively For stability For rigidity As provision for temperature related expansion/contraction

As provision for temperature related expansion/contraction

Base plate is provided on one end of long roof truss so that it can slide in case of temperature fluctuations.

Hint Answer

6. What is kinematic indeterminacy for given figure without considering axial deformation?

$What is kinematic indeterminacy for given figure without considering axial deformation?\r\n\r\n$

0 2 4 6

6

The given set of frame consists of fixed end supports with two intermediate rigid joints. Each rigid joint allows horizontal sway, vertical sway, and rotation. Therefore, two rigid joints will have six degrees of freedom.

Hint Answer

7. The degree of freedom for a pin jointed plane frame is given by 3j – m – r.

True False

False

The degree of freedom for a pin jointed plane frame is given by 2j?r, where j is number of joint and r is number of reactions.

Hint Answer

8. Calculate kinematic indeterminacy of following pin jointed plane frame.

$Calculate kinematic indeterminacy of following pin jointed plane frame.\r\n \r\n$

8 9 10 12

9

The truss is supported by hinged support at one end and roller support at or end. Hinged support in a pin jointed plane frame does not offers any degree of freedom as rotation is not considered. But roller support offers horizontal movement and hence degree of freedom is 1. For given truss, it consists of four pin joint offering two degree of freedom each. Therefore, degree of freedom is 8 + 1 = 9.

Hint Answer

9. What is kinematic indeterminacy for given figure considering axial deformation?

$What is kinematic indeterminacy for given figure considering axial deformation?\r\n\r\n$

0 2 4 6

4

The given beam is supported by roller support at both of its ends. Roller support, if considering axial deformation has two degrees of freedom i.e. Rotation and Horizontal sway. Therefore, degree of freedom of beam is 4.

Hint Answer

10. How many reaction forces are involved in a ball and socket type of joint?

1 2 3 4

3

One force acts in every three direction.
