What is a Grashof mechanism?
What is a Grashof mechanism?
Grashof’s Criterion (sometimes called Grashof’s Law, Grashof’ Rule, or Grashof’s Criterion) helps us to predict whether one Part can rotate continuously, or not. A Grashof mechanism has at least one part that rotates continuously. A simple Crank-Rocker is the best known Grashof mechanism.
What is deltoid linkage?
ABSTRACT: The deltoid linkage is a type of four bar linkage mechanism in which the length of adjacent links are equal. At such condition when one of the shorter link is fixed, then crank-crank or double crank mechanism is obtained.
Which of the following is not a kind of synthesis problem?
Which of the following is not classified under synthesis problem? Explanation: Graphical methodology can result in errors in the synthesis of a mechanism hence, it is classified as a synthesis problem. However, the remaining options do not classify as synthesis problems.
Which of the following are not included under planar mechanism?
Which of the following are not included under planar mechanisms? Explanation: Hooke’s universal joint is an example of spherical mechanism as the relative motion of the particles is three dimensional, whereas the rest are examples of planar mechanisms (the relative motion is two dimensional.)
What is Grashof number How does Rayleigh number differ from Grashof number?
The Rayleigh number is defined as the product of the Grashof number, which describes the relationship between buoyancy and viscosity within a fluid, and the Prandtl number, which describes the relationship between momentum diffusivity and thermal diffusivity.
Is the link next to the shortest link is fixed what type of mechanism is obtained?
crank rocker mechanism
Explanation: When the link next to the shortest link is fixed, the short link is able to rotate continuously and is called crank. The link opposite to it can only oscillate between limits and is called the rocker. Thus, the mechanism obtained is the crank rocker mechanism.
