QUESTION: 1

The linear velocity of a point B on a link rotating at an angular velocity ω relative to another point A on the same link is

Solution:

velocity = lω

  = ω x AB

QUESTION: 2

According to Kennedy's theorem, the instantaneous centers of three bodies having relative motion lie on a

Solution:

If three plane bodies have relative motion among themselves, their I-center must lie on a straight line, this is known as Kennedy’s theorem.

QUESTION: 3

The instantaneous center of a slider moving in a curved surface lies

Solution:

In a sliding motion, the I-center lies at infinity in a direction perpendicular to the path of motion of the slider. The sliding motion is equivalent to a rotary motion of the links with the radius of curvature as infinity.

QUESTION: 4

The given figure shows a slider mechanism in which link 1 is fixed. The number of instantaneous centers would be

Solution:
QUESTION: 5

A four bar mechanism ABCD is shown in the given figure. If the linear velocity ‘VB’ of the point ‘B’ is 0.5 m/s, then the linear velocity ‘Vc’ of point ‘C’ will be

Solution:

E i s instantaneous center for the link A B and C D and angular velocity for the point B and C would be same about E

QUESTION: 6

Examine the figure shown below wherein the numbers indicate the links:

Which of the statements given below are correct?
1. I34 is at ∞, perpendicular to QS
2. I45 is at perpendicular to QS
3. I71 is at T
4. I45 is at R

Solution:
QUESTION: 7

A line drawn through an instantaneous center and perpendicular to the plane of motion is called instantaneous axis. The locus of this axis is known as

Solution:
QUESTION: 8

The instantaneous center of rotation of a circular disc rolling on a straight path is

Solution:
QUESTION: 9

The locus of instantaneous center of a moving body relative to a fixed body is known as the

Solution:

A centrode is the locus of the I-center of a plane body relative to another plane body for the range of motion specified or during a finite period of time.
Space centrode (or fixed centrode) is the locus of the I-center of the moving body relative to the fixed body.
Body centrode (or moving centrode) is the locus of the I-center of the fixed body relative to the movable body.

QUESTION: 10

The space centrode of a circular disc rolling on a straight path is
