Simple mechanism
Element or link :-It is a mechanical member and
(i) it should hava relative motion (ii) it must be a resistant body. And (iii) it should be connected to another body.
Types of links :-
1.Rigid link :-
It is a rigid body and not having any types of deffection and solves the perpose. However, as the deformation of a connecting rod, crank etc.
2. Flexible link :-
There is a passibility of flexibility i.e., bending, extension..etc. for examples belts, rope, chains and wires are flexible links and transmit tensile forces only.
3. fluid link :-
This link is formed by using a fluid. Examples of fluid link is hydraulic presses, jacks and brakes.
4. floating link :-
A link which is not connected to the flame is called floating link.
Structure :-
It is an assemblage of a number of risistant bodies (known as embers) having no relative motion between them and ment for carrying loads having strining action. A railway bridge, a roof truss, machine frame etc.
