288) An eccentric sheave pivoted at one point rotates and transmits oscillatory motion to a link whose one end is pivoted and other end is connected to it. This mechanism has

289) Whitworth quick return mechanism is obtained by inversion of

290) In its simplest form, a cam mechanism consists of following number of links

291) Which of the following mechanisms produces mathematically an exact straight line motion

292) In a mechanism, usually one link is fixed.If the fixed link is changed in a kinematic chain, then relative motion of other links
