QUESTION: 1

Which amongst the following is wrong statements pertaining to machine and structure?

Solution:

Structure and machine both are permanent construction. e.g. structure: Roof truss, machine frame, railway bridge etc.

QUESTION: 2

The lead screw of a lathe with nut is a

Solution:

If two mating links have a turning as well as sliding motion between them, they form a screw pair. This is achieved by cutting matching threads on the two links. The lead screw and the nut of a lathe is a screw pair.

1. Oldham coupling
2. Whitworth quick return mechanism
3. Beam engine mechanism
4. Elliptic trammel mechanism

Select the correct answer from the codes given below:
Solution:

Inversion of double slider-crank chain:
1. Elliptic trammel
2. Scotch yoke
3. Oldham's coupling Whitworth quick return mechanism is second inversion of single slider chain
Beam enigne is a type of steam engine

QUESTION: 7

Which of the following is an inversion of doubleslider-crank chain?
Solution:

Except scotch yoke, all three are inversion of single slider chain.

QUESTION: 8

In a kinematic pair, when the elements have surface contact while in motion, it is a
Solution:

The two links or elements of a machine, when in contact with each other, are said to form a pair. If the relative motion between them is completely or successfully constrained, the pair is known as kinematic pair.

QUESTION: 9
