 1. Cycloidal motion.
 2. Simple Harmonic motion.
 3. Uniform velocity motion.

The graph of turning moment diagram is drawn between _____________.

According to Kennedy's theorem, if three links in mechanism are in relative motion, then their instantaneous centers lie on

The following list of statements is given:

1) Grashoff’s rule states that for a planar crank-rocker 4-bar mechanism, the sum of the shortest and longest link lengths cannot be less than the sum of the remaining two link lengths.

2) Inversions of a mechanism are created by fixing different links, one at a time.

3) Geneva mechanism is an intermittent motion device.

4) Gruebler’s criterion assumes mobility of a planar mechanism to be one.

The number of correct statements in the above list is

A compound trains consist of six gears namely A,B,C,D,E, F  which has  respectively numbers of teeth. Find the ratio of angular speed of the driven (F) to the driver (A) of the compound train:
