Probably not, at least because you haven't actually defined a problem. incidentally work equations are often much easier to write than force equations.

I have a homework where I need to pick a mechanism and write kinematic equations and dynamic force equations without any numeric values. mechanism cant be a crank biel mechanism or four- rod mechanism. But I dont know what do I need to do. I thought it would be possible to come up with dynamic force analysis based on the given information with this example.

The masses of the items and their moments of inertia are missing. Massless, inertialess items have no forces.

Once those are known the forces due to linear and rotational acceleration can be determined.

Perhaps start with a less geometrically complex linkage such as in a single piston crank mechanism as driven by the crank? Then you have the mass of the piston, the mass and rotational inertia of the connecting rod and the centripetal acceleration of the crank. This offset slider adds too many trignometric terms for a first effort.

I tried to come up with these equations. Do you guys think that these equations can be written based on the shape given in the problem.

I must suggest you please use CAD tools to solve these kind of problems they will help you out
