The number of degrees of freedom in a planner mechanism having $$n$$ links and $$j$$ simple hinge joints is

In a certain slider-crank mechanism, lengths of crank and connecting rod are equal. If the crank rotates with a uniform angular speed of 14 rad/s and the crank length is 300 mm, the maximum acceleration of the slider (in...

Match the approaches given below to perform stated kinematics/dynamics analysis of machine Analysis $$P.$$ Continuous relative rotation $$Q.$$ Velocity and acceleration $$R.$$ Mobility $$S.$$ Dynamic - static analysis Ap...

A planar mechanism has 8 links and 10 rotary joints. The number of degrees of freedom of the mechanism, using Gruebler's criterion, is

For a four bar linkage in Toggle position, the value of mechanical advantage is

The number of inversions for a slider crank mechanism is

In a four-bar linkage, $$S$$ denotes the shortest link length, $$L$$ is the longest link length, $$P$$ and $$Q$$ are the lengths of other two links. At least one of the three moving links will rotate by $${360^ \circ }$$...

The mechanism used in a shaping machine is

The lengths of the links of a 4-bar linkage with revolute pairs only are $$p,q,r$$ and $$s$$ units. Given that $$p < q < r < s.$$ Which of these links should be the fixed one, for obtaining a ‘double crank’ mechanism?
