Your Question:

According to Grashof's Law, in a flat four-bar mechanism articulated with one fixed, at least one of the bars can make a full turn if the sum of the shortest bar and the bar is less than or equal to the sum of the other two.

Grashof's law is followed by five flat four-bar or link mechanisms (An example is shown in Figure 1). In order for the bars or links of the mechanisms that comply with the law to make a complete turn, each bar must occupy different parallel planes in a real arrangement.

Step By Step Answers with Explanation

Introduction:

Grashof's Law, a fundamental principle in mechanical engineering, governs the movement of four-bar linkages. According to this law, in a flat four-bar mechanism with one fixed bar, a complete turn is possible if the sum of the shortest bar and the longest bar is less than or equal to the sum of the other two bars. This principle finds applications in various mechanical systems, and understanding it is crucial for engineers.
