This lever type has been used in the design of many devices such as a wheelbarrow, nutcracker, bottle opener, and conventional door. Lastly, third-class levers operate with the effort applied between the fulcrum and load. These levers can be found in tweezers, fishing rods, hammers, boat oars, and rakes. Pulley Figure 4.

Fig.2.6 Degree of freedom. The rigid body has 6 DOF in space but due to formation of linkage one or more DOF is lost due to the presence of constraint on the body. The total number constraints cannot be zero as the body has to be fixed at some place to make the linkage possible. Thus the degree of freedom is given by.

A lever is a stiff bar or rod that rests on a support called a fulcrum (pronounced FULL-krum) and which lifts or moves something. This may be one of the earliest simple machines, because any large, strong stick would have worked as a lever. Pick up a stick, wedge it under one edge of a rock, and push down and you have used a lever.

Based on their singular characteristic, toggle-linkage mechanisms can be used to generate a large output force from a small input force. Hence, the mechanism is particularly used for tasks that demand large forces. Yossifon and Shivpuri [1] applied a toggle-linkage mechanism to a mechanical press and analyzed the load-stroke characteristics.

What is the Quick Return Mechanism? A quick return motion mechanism is used in the shaper and slotter machine in which the circular motion is converted into reciprocating motion so that the slider moves forward and backwards. In the forward direction, the cutting process occurs while in return there is no such cutting. Quick Return Mechanism Types:

Functions of Toggle Mechanism : 1.) To multiply a hand force at the handle into a high clamping force to hold work. 2.) To create an over-center lock to prevent the clamp from opening and releasing the work until opened by the operator. 3.) To rapidly open and close the clamp giving a wide clearance in which to load and unload the workpiece.

The links are connected into a group by four joints. The design of a four-bar linkage will determine how far each body will move. The range of movement required affects the design of a four-bar linkage.

In the Standard Model, the Brout-Englert-Higgs mechanism provides mass to elementary particles. While physicists are carrying out direct studies of the Higgs boson to test this mechanism, probes of other particles with mass can also provide insight.
