use this equation and find link $=$l joint$=$j degree of freedom of space $=$landa and sumfi$=$ degree of freedom of links sumation

f$=$$($L$$J$1)+$i$$

For the given mechanisms, find the degree of freedom F$.$ Show the link numbers on the figures.

Number the links and label the joints on the figure. Write the number of links, number of joints

and types of joints in the mechanisms. Indicate if there is any redundant degree of freedom.

a$)$ Planar mechanism. Assume that slip is possible at the cam joint.

b$)$ Planar mechanism. Assume that slip is possible at the cam joint.$|$
