Which of the following property of the instantaneous center is correct?

The two rigid links have no linear velocity relative to each other at the instantaneous centre.

A rigid link rotates instantaneously relative to another link at the instantaneous centre for the configuration of the mechanism considered.

All of these

The velocity of the instantaneous centre relative to any third rigid link is same whether the instantaneous centre is regarded as a point on the first rigid link or on the second rigid link.

A shaft has an attached disc at the centre of its length. The disc has its centre of gravity located at a distance of 2 mm from the axis of the shaft. When the shaft is allowed to vibrate in its natural bow-shaped mode, it has a frequency of vibration of 10 rad/s. When the shaft is rotated at 300 r.p.m., it will whirl with a radius of

The Kutzbach criterion for determining the number of degrees of freedom (n) is (where l = number of links, j = number of joints and h = number of higher pairs)

n = 3(l - 1) - 3j - h

n = 2(l - 1) - 3j - h

n = 2(l - 1) - 2j - h

n = 3(l - 1) - 2j - h

n = 3(l - 1) - 3j - h

n = 2(l - 1) - 3j - h

n = 2(l - 1) - 2j - h

n = 3(l - 1) - 2j - h
