A crank and slotted lever mechanism used in a shaper has a centre distance of 300 mm between the centre of oscillation of the slotted lever and the centre of rotation of the crank. The radius of the crank is 120 mm. Find the ratio of the time of cutting to the time of return stroke.

Simple Mechanisms topics: Simple mechanisms, kinematic links and chains, links types, mechanism, grublers criterion, single and double slider crank chain inversions, kutzbach criterion applications, kinematics chains and its types. A simple mechanism is a mechanical device that uses mechanical advantage to multiply force and change the direction or magnitude of a force. A mechanism with four links is considered a simple mechanism.  Here are some examples of simple mechanisms: Lever: A rigid body that can rotate on a point on itself. A lever is a bar or board that rests on a support called... Show more
