The number of degree of freedom of a planer linkage with 8 links and 9 simple revolute joints is
Which of the following equations represents Kutzbach's modification of Gruebler's equation for planar mechanisms: Given that: M = degree of freedom or mobility, L = number of links, J = number of full joints G = number of grounded links
A simple mechanism consists of 11 simple revolute joints and 9 links. What is the degree of freedom of the mechanism?
The figure shows a mechanism with 3 revolute pairs (between the links 1 and 2, 2 and 3, and 3 and 4) and a prismatic pair (between the links 1 and 4). Which one of the four links should be fixed to obtain the mechanism that forms the basis of the quick-return mechanism widely used in a shaper?
The lengths of the links of a 4- bar linkage with revolute pairs only are p,q,r and s units. Given that p < q < r < s and s+p < q+r which of these links should be the fixed one, for obtaining a ‘double crank’ mechanism?
The lengths of the links of a 4-bar linkage with revolute pairs are p,q,r, and s units. given that p
A planar four-bar linkage mechanism with 3 revolute kinematic pairs and 1 prismatic kinematic pair is shown in the figure, where AB ⊥ CE and FD ⊥ CE. The T-shaped link CDEF is constructed such that the slider B can cross the point D, and CE is sufficiently long. For the given lengths as shown, the mechanism is
The Kutzbach criterion for determining the number of degrees of freedom (n) is (where $$l$$ = number of links, j = number of joints and h = number of higher pairs)
Consider the following statements: I. The degree of freedom for lower kinematic pairs is always equal to one. II. A ball and socket joint has three degrees of freedom and is a higher kinematic pair. III. Oldham’s coupling mechanism has two prismatic pairs and two revolute pairs. Which of the statements given above is/are correct?
