3. A linkages of a front-end loader which is driven by two hydraulic cylinders is shown in FIGURE Q3. a. Sketch a fully-labelled kinematic diagram of the linkages. [10 marks] b. Determine its degree of freedom by applying Gruebler's equation. [9 marks] c. If the number of degrees of freedom is increased by one to the value obtained in part (b). Asses whether the system has any benefit or drawback to the linkages.
Expert Answer
SOLUTION : Firstly we have to numbered differnt links - Link 1 = fixed link (G,H) Link 2 = GHED Link 3 = Hydraulic cylinder (i) (HF) Link 4 = EC ; Link 5 = (CB) Link 6 = AB ; Link 7 = Hydaulic cylinder (ii) (CD) Link 8 = Load carrier
