Grashof's law
WebWhat is Grashof’s Law. 1. The law states that for a four-bar linkage system, the sum of the shortest and longest link of a planar quadrilateral linkage is less than or equal to the sum of the remaining two links, then the shortest link can rotate fully with respect to a neighbouring link.

WebDec 7, 2024 · FOUR BAR MECHANISM. This mechanism consist of 4 links and 4 turning pairs. One of the most useful and most common mechanisms is the four-bar linkage. In this mechanism, the link which can make complete rotation is known as crank. The link which oscillates is known as rocker or lever. The link connecting these two is known as coupler … WebGrashof's Law: Examples. In this video, we want to practice how to apply the Grashof's law for a four-bar linkage. You will see 2 types of examples. In some of them, the lengths of all the links are given and we need to predict the type of motion (which is straightforward and easy); whereas, in some others, we need to determine the range for ...
