• 5

• 6

Scleronomic constraints are

• time dependent

• time independent

• 4

What is the order of Lagrangian equation ?

• 1

• 2

• 3

• 4

Lagrangian function is defined by

• L= T-V

• L=T+V

• L=F-V

• L=F+V

The constraints on a bead on a uniformly rotating wire in a force free space is

• Sceleronomous

• Rheonomous

• both a and b

• none of these

Generalized coordinates

• depend on each other

• independent on ecah other

• necessarily spherical coordinates

• necessarily cartesian coordinates

A non holonomic constrain may be expressed in the form of

• equality

• inequality

• vector

• none of these

Lagrangian is function of

• position only

• velocity only

• time only

• all of the above

The number of independent coordinates required are called

• generalized coordinates

• Cartesian coordinates

• cylindrical coordinates

• spherical coordinates
