A slider moving on a fixed link having constant radius of curvature will have its instantaneous centre at the centre of the circle.
-
According to Kennedy's theorem, if three bodies move relatively to each other, their instantaneous centres will lie on a
-
The tangential component of acceleration of the slider with respect to the coincident point on the link is called coriolis component of acceleration.
-
The periodic time is given by (where ω = Angular velocity of the particle in rad/s)
-
When two links are connected by a pin joint, their instantaneous centre lies
-
The direction of linear velocity of any point on a link with respect to another point on the same link is
-
In a differential band brake as shown in the below figure, the drum rotates anticlockwise and the greater tension T1 acts at A and smaller tension T2 at B. Length OA is greater than length OB. In order to apply the brake, the force P at C should
-
The periodic time of a compound pendulum is __________ when the distance between the point of suspension and the centre of gravity is equal to the radius of gyration of the body about its centre of gravity.
-
When the pitching of a ship is upward, the effect of gyroscopic couple acting on it will be
-
The unbalanced force due to reciprocating masses
