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
velocity = lω
= ω x AB
According to Kennedy's theorem, the instantaneous centers of three bodies having relative motion lie on a
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.
The instantaneous center of a slider moving in a curved surface lies
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.
The given figure shows a slider mechanism in which link 1 is fixed. The number of instantaneous centers would be
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
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

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
The instantaneous center of rotation of a circular disc rolling on a straight path is
The locus of instantaneous center of a moving body relative to a fixed body is known as the
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.
The space centrode of a circular disc rolling on a straight path is
